Help! My cat peeing bright red urine.
b0bbied0ll posted:
We're pretty sure our 4 year old female cat has a UTI. She was squatting in the house and having only a few drops of clear urine come out at a time. I took her to the vet yesterday and she got some antibiotics. She has been on them for 24 hours now and this morning she is still squatting but now the drops of urine have blood in them. It is quite a bit of blood and the sample I have been gathering for the vet is bright red. I'm taking it to the office tomorrow for a urinalyses but I am really worried about her. She has always been a healthy cat.
Drew Weigner, DVM, ABVP responded:
It sounds like your cat has cystitis, the generic term for inflammation of the bladder. Infections are one common cause, but there are many other causes. If she actually has an infection, the antibiotics may work in several days if it's the correct one (a culture and sensitivity will tell you.) But if it's not an infection, the antibiotics won't help much. Regardless, we often add anti-inflammatory medication to the treatment as it gives them rapid relief.
