Sad today. Senior cat (Stormy, who's either 16 or 17 now I'm not sure anymore) seems to be rapidly declining. I weighed him 2 weeks ago and he weighed 13.2 lbs. This morning I weighed him and he was only 12 lbs. The past couple days he's going potty just outside the litter box and today he won't eat anything, not even the chicken baby food I made. Trying to get him into the vet sooner rather than later. We lost Rascal (his brother) 2 years ago this month. He's been a member of our family since he was a tiny kitten. I'm not ready to say goodbye. But we need to know if the howling he's been doing and the other stuff is because he's in pain, or cat dementia, or something else.

eta: I just got a vet appointment for tomorrow afternoon.
