Why is my old cat not eating, losing weight, and peeing randomly?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female

Hi, could you offer any advice re my cat? She came in to the house with a swollen cheek last week, swelling seemed to go down over a few days but she is struggling to find motivation to eat and we have to entice her with a treat. Struggles to leap onto the sofa and occasionally loses balance. She's not cleaning herself as well as usual. Miaowing more and constantly wants attention. Settling less on our laps. Urinating in random places in the house. Lost some weight. Approx 12 year old tabby.

It sounds like there are a couple of things going on with Abigail at the moment. She could have an abscess in her cheek causing the swelling. That could be brought on by a fight with another animal or by a dental problem. An abscess will be painful, and that would keep her from wanting to eat. It would make her mouth sore as well, especially if she has a dental problem, and she will not want to use her mouth to clean herself. The problems with leaping onto the sofa and balance could be due to arthritis or joint issues, while the weigh loss and urination could be due to kidney disease, diabetes, or hyperthyroidism. I would have her seen by a vet first thing Monday morning for a physical exam, geriatric blood panel, urinalysis, and potentially x-rays. Using these tests, the vet can diagnose what is causing all her symptoms, and can discuss treatment options with you.
