Rated 5 out of 5 by from Used this for my cat My cat had been suffering from a terrible ear infection and was rapidly losing weight (she is tiny and at a year old she was half the weight she was 6 months ago). My vet thought that because of the ear infection she wasn't eating because her equilibrium is off and she felt nauseous (made sense to me!). He gave her an anti-nausea shot and we treated the ear infection, and he suggested this food for her to gain weight. She loves it! The first week she gained 4 ounces back (a big deal when you weigh 4 lbs). I haven't weighed her recently but she is starting to fill out. My only problem is...where can I buy this other than my vet? Oh and the other problem...my other dogs and cats (who do not have a weight problem) want to eat it!!
