DVM360 has some really interesting, and quick interactive cases you can read and participate in. Case #8 which is featured today is "Why won't this cat eat" and gives you some symptoms to try to analyze and treat. Vet techs and vets might be bored with it but the rest of us might me interested in it. It's also a good learning tool. I didn't know whether to post this here on in the lounge.
