H took the cat to our usual vet this morning. She doesn't think it's his time yet. She also doesn't think he's in any pain. He *is* anemic and has low potassium. She's having us give him an appetite stimulant and supplement iron and potassium. We'll follow up with her in 2 weeks.
This is not the kind of roller coaster I enjoy. I'm glad it looks like we have more time with him, though. And I can guarantee he will be eating better than we are. He's already getting lunch meat turkey, but I'm also going to make him steak and chicken.
