My cat won't eat after urinary blockage and catheter. Are kidneys harmed?

Updated on September 23rd, 2025

Pet's info: Cat | Himalayan | Male | 3 years and 1 month old | 9 lbs

My male cat was blocked for one day and urine catheter is made up for him 2 days ago. Since then, he refuses to eat and I force feed him. Is it expected that his kidneys got harmed or failed?

HI, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Do-Do!

When cats are blocked for a long time they can have elevated kidney and potassium values that with IV fluids and relieving the obstruction the elevations usually return to normal MOST of the time. Was blood work done when he was hospitalized? I would have him rechecked and blood work ran since it has been 2 days with out eating. Cats shouldn't go longer than that as they can get a secondary liver problem from not eating. If you changed his diet to a prescription urinary diet consider going back to his old food until he is eating and urinating well then trying the prescription food again. There are also other brands to try.

I wish you the best!

    I'd take Snowball back into a vet immediately. It's extremely serious when a cat won't eat or drink, and it's concerning he can't take his medication because he won't eat. He needs veterinary care now, please take him into a vet right away. Best of luck.
