My vet told me that I should not give the cat insulin unless he eats. The cat is eating less and less everyday and dropping weight fast. We took him back to the vet and she said it is most important that we get him to eat and that we should feed him ANYTHING that he will swallow. We have changed his food many times and he seems to like the food for a day or two and then won't eat it anymore so change again. He will like the new food again for a day or so and then refuses to eat it anymore. Any suggestions?
