Are there any tricks out there to get your cat to eat. His health made a turn for the worse just recently (he's almost 18 years old). He has gone blind and won't eat or drink. The vet says that he may be in shock from loosing his sight and may come around, but that just hasn't been happening. I feel bad because he has to be very hungry by now, but he just won't eat. I've even tried tuna fish, put it right up to his nose and he just isn't interested. Same with his water bowl.
