Sounds like a neat idea. If you have a local office of the Diabetes Association (not sure what it is called in the USA), they likely publish a newsletter - online as well as hard copies.

Give them a call - see what they think! Your organization might get a free ad in the newsletter, or even a writeup.

What a great chance to place some hard-to-place kitties!

I wonder if the same would work for the FIV kitties?
