My male cat was just diagnosed with FIC (Feline Idiopathic Cystitis) a week ago. It causes inflammation in the bladder and crystals making it hard for him to urinate. He hasn't went to the bathroom in 2 days and he doesn't have much longer before either kidney failure or his bladder bursts. I've already spent 1674 at the vet. He really needs a 24-hour vet but they are very costly. He is walking slowly and meowing in pain going back and forth to the litter box with no change. I'm not even sure if he will be with us by tomorrow but I am trying.. I would greatly appreciate any help.
