I am wondering why my cat peed right beside her litter box. She never misses, it was very clean and she has two to choose from. It was a LOT of pee too. I don't want to drag her to the vet for one pee. She's a cat, obviously would prefer to die before going there. I just know that she is getting very old and could be anywhere from 15 to 20, just a guess as she won't tell. Is this what elderly cats do occasionally? Her appetite is good, she grooms and is very mobile and spoiled quite properly. Should I just keep an eye on her and take her to the vet if it happens again. What would you do? Thank you!🤔
