I got my cat from the RSPCA 6 years ago, she was between 8-12 at the time. It’s not been easy, she’s a stranger to the litter tray (probably why she was dumped) and tends to go anywhere but we manage. Over the last few days she’s changed, she wants to sit on my knee a lot, wanders around and doesn’t settle much. Appetite is keen but hardly eats (she has no teeth at all) and stares at me a lot. Last night she attempted to go outside when I let the dogs out for the last wee despite not going out for over a year, I didn’t let her cos she just seems so old. She’s recently had full vet check/blood tests all fine. She’s very very thin, I’ve been feeding tiny meals frequently, she always eats but small amounts. I’m wondering if she’s confused or demented? I don’t want to take her to the vet, I think she’s very old and she’s been checked out. Is there anything else I can do ? What should I expect?
