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
