So, just FYI...our oldest (?) cat was diagnosed with a lung tumor last week, and the vet recommended that, rather than put him through a lot of procedures that wouldn't be much help, we just let it run its course. We were pretty sure, based on his appetite and movement, that we had a week or two left with him, but his breathing suddenly got much worse tonight. He already has a vet appt for the morning, so we're going to see what they say. I'm fairly certain he won't be coming back from that appointment. But...I'd rather that than have him go through seizures like our previous cat did.
