Why is my cat still spraying after UTI and bladder stone treatment?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 8 years old | 15.4 lbs

He keep spraying pee to floor & corner of cage alot since Nov21. He does urine inside litterbox everyday. On 8-Jan, he tried pee few times within short period but only little urine with some blood 3 times. The blood is like discharge. I have brought him to vet. He is on antibiotics, UTI supplement & acid urine as Dr diagnosed him with UTI & bladder stones. After that, he can pee well. He usually does more water. Only concern now is the spraying of pee. Is it related? What should I do?

Hello, thank you for using Petco Pet Education Center, formerly Petcoach.

I cannot tell you for certain whether the spraying is associated with the current urinary issue or if it is a behavioral issue. If I had to guess, I would say it is likely related to his current medical situation. You need to talk to your vet about this as they have all his medical information that I do not have.

I'm also assuming he has bladder crystals and not stones? If he has stones then he would need surgery to remove them and that may be why the urinary is bloody. You need to clarify that with your vet.

Please take Miu Min back to your vet for a follow-up and to discuss.
