Why is my senior cat having accidents, meowing, and not eating?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 18 years and 5 months old | 8 lbs

My cat is hyperthyroid and has dry eye. Recently I believe she has developed dementia as she meows out of the blue. She has also been going to the litter box, but not peeing in it. She pees outside, and she has been pooping in the house. Within the last two days I have caught her peeing on the carpet wherever she wants. She hasn't been eating that much, but she still drinks. I am concerned that I need to prepare myself for the end and I'm wondering if these signs corroborate my feeling. Help

I'm so sorry that Cleo is having these problems. Since you mentioned that she is hyperthyroid, I would be sure to check her thyroid level and her blood pressure. If either is high, it could be responsible for the behavioral changes that you are noticing. I would also recommend checking a urine sample since urinary tract infections are common in older female cats to make sure that isn't playing a role in her sudden changes. Cleo is certainly an older girl and not eating as much is certainly a worrying sign, but I would make sure there isn't any treatable explanation for her recent behavioral changes.
Good luck! I hope that was helpful and answered your questions. Thanks for using Petco Pet Education Center, formerly Petcoach.
