My little girl, Chickpea, is 17 years old. She does have some heath issues like IVDD and hyperthyroidism. But those things were kept in check and she still seemed herself the past year or so. We needed to up her hyperthyroidism medication by a lot the past month and since then, she seems different. Not totally different but there's a change. She still eats and drinks, goes to the litter, and cuddles but she's less responsive and really really clingy. (She's always been attached to the hip to me but now really doesn't want to leave laying on me.) I think it's the less responsive part that is making me unsure. She seems in a daze a lot of the time. She also has good days and bad days. Some days she is more her. I've asked the vets, none of them have said it's time but they say to monitor her and check her quality of life. I've had to do this before and it was obvious with another cat, who has declining quick and having seizures. I want to do right by her and not sure if she is in pain or just slowing down. I think about my other cat and of course, have the "what ifs" with that. I know it's hard to answer but how do you know?Do I let it get to the point of being obvious (not going to the toilet or eating?)
