Why is my cat peeing outside the litter box and has diarrhea?

Updated On September 23rd, 2025

Pet's info: Cat | Ocicat | Female | spayed | 13.5 lbs

Hi, how are you? My cat, Rose, has been peeing outside of the litter box for about 5 days now. She will pee on the foot of my bed (under the covers), or on dirty clothes. Her pee doesn't smell like ammonia at all and it normally has a medium to strong smell of ammonia. She isn't peeing in the litter box at all and I'm afraid she is going to ruin everything. Her litter is scooped daily to every other day. Last night she also starting having diarrhea in her litter box, but isn't covering it up.

Hi there! I'm fine, thank you, hope you are doing well :-) Not using the litter box can be a sign of a medical illness, such as a UTI or bladder stone. I would recommend taking Rose into your vet today for an exam. Your vet can do routine blood tests and a urinalysis to see if she does have a UTI or bladder stones. If she has a UTI, she will need antibiotics to treat it. Bladder stones may need to be removed surgically, or can be managed with diet. As for the diarrhea, that could be caused by a GI illness, stress, eating something rotten, or a foreign body. If Rose has a medical illness, that will be stressful for her, and it could be the cause of her diarrhea. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
