Memories: Journal of Feline Medicine and Surgery uses my images

Biology, My work in print, Photography, , , ,

I got a little reminder today of a neat use of my images: the Journal of Feline Medicine and Surgery purchased two of my cat tongue closeups to illustrate an article on the medical implications of cat hairballs.  The article was behind a paywall when it was first published, but the full text is now freely available.

Here’s the reference:  Cannon, M. 2013. Hair Balls in Cats: A normal nuisance or a sign that something is wrong? Journal of Feline Medicine and Surgery 15: 21-29. doi: 10.1177/1098612X12470342.   http://jfm.sagepub.com/content/15/1/21.abstract

 

A new member of the family: Bertie!

Pets, Photography,

Last week we got a new family member: Bertie!

We weren’t planning on adding another family member (haven’t you heard that before?), but Bertie adopted us and we couldn’t turn him down. Bertie is, as you can tell from the pictures, a blue tabby and white domestic shorthair cat.

Lazy day

Bertie was a stray; we first met him when he meowed outside our window as we were feeding our own cats. He was super-friendly right from the start, wanting no end of petting and company. We ended up catching him, and discovered (thanks to his chip) that he was an abandoned kitty: the owner registered on his chip no longer wanted him. 🙁

I was abandoned 🙁

So, we’ve decided to give Bertie a home, with the blessing of the prior owner. He’s currently indoors, isolated from our other two cats as we wait on test results to make sure he won’t transmit anything to them. When we first met him he was starving and thus wolfing down food (he hunts about as well as your average pine tree), but he’s back to normal eating habits now. He’s also spent nearly all of his non-sleeping hours grooming himself.

Bertie is definitely into comfort:

Support a good cause, if you so desire

OCC, Pets, Photography

I’ve just entered two pictures into the Humane Society’s World Spay Day photo contest.

Kira, a brown tabby, relaxing on a shelf next to a brick wall. I love how she looks mildly inquirous while also looking serenly peaceful and comfortable. She's also got her paws cutely folded up underneath her. How cat like! (Marc C. Perkins)
Listening Cat is Happy to Hear About Your Problems
Lucca looking decidedly unimpressed. This picture reminds me of a typical LOLCat image (e.g., http://icanhascheezburger.com); I think the caption would be something like "Unimpressed cat is unimpressed", "Meh", or "Is it really Monday already?". But, sadly, I won't be submitting it to that website, as their terms of service for uploaded images give them way too many rights for free (http://corp.cheezburger.com/legal/terms-of-service/). (Marc C. Perkins)
Unimpressed Cat is Unimpressed

I personally donate to the Humane Society, and am happy to help a good cause. As such, in addition to entering my images into their judged category, I’ve also entered them into their “fundraiser” competition. In this competition the entries compete for votes, which can be obtained by donating to the Humane Society:

“Kira”

Vote

“Lucca”

Vote

There’s no way I can win the fundraiser category, and I don’t want to try1. Instead, I want to use this as an opportunity to give you an excuse to donate a little something to a worthy cause. And, just to reinforce the idea that I’m not in this for the fundraiser competition prize, if I do somehow win I’ll donate the prize (an iPad 2 and iPod) to the Orange Coast College Disabled Students Center.

The contest ends February 29 at 10:00pm EST, so donate before then if you desire (by following the links above).

1 Votes are tallied per individual picture, not per photographer. So, by posting two pictures I’m possibly splitting any votes I get. But this way you get to vote for your favorite of my two cats!

Cat eyes on a Friday

Pets, Photography,

Last weekend I got a few more pictures of my cats, this time focusing on the eye (as opposed to the tongue or third eyelid). Lucca was a great model with her beautiful green eyes and blue patched tabby and white fur:

A closeup of Lucca, a blue patched tabby and white shorthair house cat, looking up at something exciting. I like her attentive, alert expression that shows off her cute "old rose" nose and her bright green eyes. The fur on the top of her nose is also in sharp focus, showing off the different directions it lays. The background is off white, and out of focus. (Marc C. Perkins)
What's up there?
This vertically-cropped image is a closeup of a blue patched tabby and white domestic shorthair cat's face, focusing on the eye. I don't take too many vertical images of my cats up close, and often don't like them, but this is an exception. (Marc C. Perkins)

Eye closeup: looking in or looking out?

The first one makes a great desktop background (and no, I’m not biased at all …); in fact, I can see Lucca’s nose and whiskers poking out just to the right of the window I’m writing this in 🙂

Have a great weekend!

Cat anatomy: the barbed tongue

Biology, Pets, Photography,

I recently found myself sorting through a folder that contained a few dozen pictures of my cats in various poses, the sole consistent element being that they were sticking their tongues out at me. How this came to be started with this image:

Lucca closes her eyes as she licks her paw, showing off dozens of her tongue barbs (filiform papillae). I love cats cleaning themselves! (Marc C. Perkins)

I was sitting in my living room watching Lucca clean herself, as cats do, and I took a few pictures of her, as I do. But when I processed the images and saw her tongue in this one, I was entranced. I’d always known that cats have barbed tongues, but knowing something and seeing it are two different things. I then set about to get a few good images of cat tongues, and the above-mentioned folder of dozens of tongue-sticking-out images resulted.1

When cats clean themselves, their tongues are typically out for far too short of a time to see the barbs in any detail with the naked eye (at least not with my eyesight). And the tip of the tongue, which is the most likely part of their tongue a human will see, actually has no long barbs, as Kira kindly demonstrates in this picture:

Kira, a brown tabby, licking Lucca, a blue patched tabby and white. Only the tip of Kira's tongue is out, showing how the tip of a cat's tongue is lacking in the large barbs (filiform papillae). However, a few small ones can be seen on the tongue near her mouth. (Marc C. Perkins)

Getting tongue pictures showing the barbs was not trivial2, but for those of you looking for closeups of cats naturally licking, here are three closeups showing a front, three-quarters, and side angle:

A closeup of a cat's tongue from straight-on as the cat licks a sheepskin rug. Numerous barbs (spines; filiform papillae) are clearly visible across the width of the tongue. The papillae are largest in the middle of the tongue, and get progressive smaller towards the edges of the tongue. See the cropped version of this image for more detail on the tongue. (Marc C. Perkins)

A closeup of a cat's tongue from a three-quarters angle as the cat licks a sheepskin rug. Numerous barbs (spines; filiform papillae) are clearly visible across the width of the tongue. The papillae are largest in the middle of the tongue, and get progressive smaller towards the edges of the tongue. The three-quarters angle allows the viewer to better see the height of the barbs. See the cropped version of this image for more detail on the tongue. (Marc C. Perkins)

A closeup of a cat's tongue from a side view as the cat licks her paw (with a single claw and pads visible). Numerous barbs (spines; filiform papillae) are clearly visible across the top surface of the tongue. this side view emphasizes the height of the barbs (the largest are almost half the thickness of the tongue), and shows that they're angled back only slightly. See the cropped version of this image for more detail on the tongue. (Marc C. Perkins)

The barbs or spines are called filiform papillae. They’re opaque, hardened with keratin, and arise from widened bases that cover the tongue. The barbs are longer in the center of the tongue, and slowly get shorter towards the sides and front. These are what makes a cat’s tongue feel rough, like sandpaper, when it licks you.

The details on barbs may be a bit tough to see in those pictures, since they’re all essentially uncropped (to show context); but here’s what you really came for: closeups of the tongue focusing on the papillae3.

This is a crop of the "Cat tongue closeup: front view" image, focusing on the tongue. The original image is a closeup of a cat's tongue from straight-on as she licks a sheepskin rug. Numerous barbs (spines; filiform papillae) are clearly visible across the width of the tongue. The papillae are largest in the middle of the tongue, and get progressive smaller towards the edges of the tongue. (Marc C. Perkins)

This is a crop of the "Cat tongue closeup: 3/4 view" image, focusing on the tongue. The original image is a closeup of a cat's tongue from a three-quarters angle as the cat licks a sheepskin rug. Numerous barbs (spines; filiform papillae) are clearly visible across the width of the tongue. The papillae are largest in the middle of the tongue, and get progressive smaller towards the edges of the tongue. The three-quarters angle allows the viewer to better see the height of the barbs. See the uncropped version of this image for more context. (Marc C. Perkins)

This is a crop of the "Cat tongue closeup: side view" image, focusing on the tongue. The original image was a closeup of a cat's tongue from a side view as the cat licks her paw . Numerous barbs (spines; filiform papillae) are clearly visible across the top surface of the tongue, and additional papillae (fungiform papillae) are visible on the side and bottom of the tongue. This side view emphasizes the height at attachment of the barbs (the largest are almost half the thickness of the tongue), and shows that they're angled back only slightly. This is also one of the few images I've seen showing the back of a cat's tongue in a natural position. See the uncropped version of this image for more context. (Marc C. Perkins)

Friendly cats often groom each other, and so I absolutely have to include a picture of Lucca cleaning Kira while showing off her tongue barbs:

Lucca, a blue patched tabby and white cat, licks Kira, a brown tabby. I love it when cats curl up together on a couch and groom each other! Lucca's eyes are closed while her tongue is extended, which clearly shows the filiform papillae (spines or barbs) on the top surface of the tongue. Her nose, whiskers, fur, and closed eyes are also clearly in focus. (Marc C. Perkins)

And I can’t resist ending with a silly picture of Kira looking cross-eyed as she cleans her front paw:

Kira, a brown tabby, grooms her front paw, which is curled over super-cutely. I love this image because of Kira's wacky expression: she looks almost cross-eyed, and almost seems to be sticking her tongue out at the camera. Instead, she's just licking her front paw, which is folded back towards her face, showing you the very dense concentration of filiform papillae (barbs or spines) on her tongue. (Marc C. Perkins)

1 Try looking at 40-odd pictures of someone sticking their tongue out at you; it’s an odd experience.
2 It helps that Lucca goes through phases where she licks a sheepskin rug regularly.
3 Yes, these three tongue closeups are indeed just crops of the pictures above.  Have I mentioned how much I love my Canon 60mm macro lens, and just how insanely sharp it is?

Cat anatomy: the third eyelid

Biology, Pets, Photography

Most humans are probably familiar with the two fleshy eyelids we use to protect our eyes. Most vertebrates, however, have a third eyelid that they can also use to cover their eye. This eyelid is usually a thin white membrane that moves horizontally across the eye, and is called the nictitating membrane or palpebra tertia.

The third eyelid is often difficult to see in cats (and dogs), because if their outer eyelids are open then the nictitating membrane is almost always also open. However, last week when getting a few pictures of my cats relaxing, I discovered that I’d captured a sequence of pictures that clearly demonstrate the third eyelid:

Lucca shows off her third eyelid in this sequence of four photographs taken just after she woke up from a nap. The third eyelid (nictitating membrane or palpebra tertia) is a thin white membrane that slides horizontally across the eye underneath the outer two eyelids. Humans lack this third eyelid, but most other vertebrates have it. Lucca here is simultaneously stretching, yawning, and opening her eyes. In the first image her eyes are completely closed, in the second image her outer two eyelids are partially open, but the nictitating membrane is still entirely covering the eye, in the third image the outer two eyelids are almost entirely open and the nictitating membrane is about half covering the eye, and in the fourth image all three eyelids are fully open. (Marc C. Perkins)
Lucca, a blue patched tabby and white adult female cat, shows off her third eyelid in this sequence of four photographs taken just after she woke up from a nap. Lucca here is simultaneously stretching, yawning, and opening her eyes after waking up from a nap.

In the first (top) image Lucca’s eyes are completely closed and she’s just starting a yawn after waking up from a nap. In the second image her outer two eyelids are partially open, but the nictitating membrane is still entirely covering the eye (the nictitating membrane is visible as a white layer completely covering the eye; compare the second picture to the third and fourth and note that you can’t see her green eyes at all in the second picture, even though the two outer eyelids are open).

In the third image the outer two eyelids are almost entirely open and the nictitating membrane is about half covering the eye, and in the fourth (bottom) image all three eyelids are fully open.

Cat pictures to start the week

Pets, Photography

This Thanksgiving holiday was a good one. Great dinner with friends, fun street photography on Black Friday, and a weekend of relaxing with Michelle. Since I’m in a great mood, I figured I’d start the week off with a couple of kitty pictures. What could be a better start to the week?

A closeup of Lucca's hind paw, with her beautiful green eye and nose staring at you from the background in soft focus. Her paw pad leathers are multicolored because she's a dilute caliby (blue patched tabby and white), so the leathers are patterned just like the rest of her is. The leathers are a mix of two colors: blue (dilute black) and pink/rose. The texturing on the pads is also visible; it's like she's got all-terrain tire treads on her paws :) (Marc C. Perkins)

Over the past few days I’ve spent some time trying to get closeups of my cats cleaning themselves, some of which I’ll be posting in a week or two.  In the meantime, though, I got a couple of more general shots I thought I’d share:

Lucca peers off into the distance while being backlit by the setting sun. I love her mostly-closed pupils in her green eyes, and the highlighted whiskers (both nose and eyebrow). If you look closely, you can even see her eyelashes :) (Marc C. Perkins)

New macro lens!

Pets, Photography, Reviews,

A few days ago our friendly neighborhood UPS driver delivered my new Canon efs 60mm macro lens. Excitement ensued!

My primary lens to date has been a Canon efs 15-85mm. It’s an excellent all-around lens, and it even holds its own as a macro lens. But I’m already in love with the 60mm. It’s a true 1:1 macro lens that’s small and light, meaning I can carry it around easily (335g compared to the 625g Canon 100mm L). One complaint some people have is that the working distance at 1:1 magnification is only a few inches from the front of the lens, but since I do primarily plant and lichen work I don’t mind. The Digital Picture has a good review of the lens here.

Of course I just had to try out the new lens as soon as I got it. Looking around the house for items to photograph revealed one very cute and furry critter sitting next to the window.

The light was fairly diffuse room lighting, but the lens was capably able to handle it opened up nice and wide.

Yes, closeup pictures of cat eyes are a cliche, but how can I resist taking a piture of Lucca's green eyes with my new macro lens? (Marc C. Perkins)

And, of course, it was fun to play with selective focus.

I love what happens at f2.8. This picture gives me a feeling of fear: it's like a giant cat is suddenly so close that your eyes haven't had time to focus on the iris yet. (Marc C. Perkins)

After my fifteen minute, hand-held shoot with only sunny-window-enhanced room lighting, I’m very impressed.  The lens is light, quick to focus, and sharp.  I can’t wait to use it more.

My cats eat grass

Pets, Photography, Products, ,

Cats are carnivores: their skull, jaws, and teeth all cry out “I’m a hunter. I eat things like you (but smaller) for breakfast.” Yet cats in both the wild and captivity consume grass voluntarily.

A good friend bought our cats some wheat grass as a welcome-home-from-the-shelter present when we adopted them, and both enjoyed nibbling on it. Unfortunately, though, we recently learned that one of our cats has a wheat allergy, and the vet wasn’t sure if the allergens being tested for were in the grain or the leaves. So, we stopped buying wheat grass for them.

But wheat isn’t the only grass out there. In fact, Wikipedia reports that oats are often called “cat grass”. So, we ordered some tack oats from Johnny’s Selected Seeds and planted it last week. Both Lucca and Kira have been eying it through the window as it grew, and today we brought the pot in for them to eat (it took about a week to go from seed to cat-ready size).

Within a few minutes both kitties were investigating:

Lucca sniffs a pot filled with newly germinated (and nibbled on) oat grass (tack oats; Avena sativa). (Marc C. Perkins)

Photographing animals at the Newport Beach Animal Shelter

Orange County, Pets, Photography, , , , ,

I’ve started volunteering with the Newport Beach Police Department’s Animal Control Unit to take pictures of their dogs and cats so they can add pictures to their Petfinder website. Last week was my first session with them, and I had a great time photographing about 20 animals in one afternoon.

First up were the dogs. Many of them were super-exited to be let out for a photography session, and thus just a smidgen hyper.  But this white husky was downright calm:

And lots of the dogs had perfect “adopt me” expressions
