Just like regular doctors, there are good vets and poor ones. Our 15 yr old adopted tabby was wasting away to skin and bones a couple of yrs ago as he couldn't keep anything down. Basically he was extremely dehydrated, bony, sunken eyes etc. The vets did a lot of "work" on him with little success with the exception of re-hydrating his little body and figured it was mostly his age which was his problem...after spending a couple of thousand at the vet, we found out there was a quiet recall(e coli?) from a pet store on the premium all natural food we were giving him. Tried several other different types of food until we found one he could keep down...we're not sure how much damage that bad food did to his insides a couple of years ago as he's had a couple of minor relapses along the way since, but we always consider the food as being one of the main reasons for his problems. We always feed him the best natural cat food we can find and have settled on one with very, very minimal ingredients which seems to be working. So I'll say, always consider the possibility of a problem with the pet's food if they aren't feeling well and don't always believe everything a doctor/vet may tell you, they can be wrong.
