My 11 year old Persian cat was very lethargic and not eating or drinking yesterday. I took him to the vet. After all the blood work, X-rays, and urinalysis all results were negative. He does have a bad upper respiratory infection which is thought to be the cause of all of this. He has been given fluids, antibiotic injection, and steroids to come home with. He is now home. He’s more lively, breathing better, and eating. He hasn’t used the litter box in 24 hours. When should I be worried?
