My moggy stopped eating entirely early last week following a steady decline in appetite 2 weeks after we moved house. He was diagnosed with the cat flu. He seemed to regain his appetite and ate nearly an entire can of a Low calorie (28 calories) Japanese cat food on Sunday. He ate very little on Monday, then ate 12 rectangular lumps of Royal Canin renal tuna on Tuesday, then at 3 am on Wednesday I stupidly accidentally fed him a tuna broth containing onions ( I thought it was just tuna water, which was what it said on the can), which he lapped up. He’s been vomiting on Wednesday and today (I’ve been syringe feeding him this entire time and he never once vomited, so it’s definitely the onions. The vet told me he might vomit for a few days) He got an anti vomiting injection today. I gave him Remeron today, but it hasn’t taken effect. Has anyone’s cat quit eating and subsequently recovered?
