Jen, Schmitty started sleeping really heavily during the last 2 years of his life. I think that’s perfectly normal but I am no vet, that’s for sure. Sometimes, I would go in and touch him and when he was a little guy he used to wake up immediately. But later on it took a few pets and talking to to get him to come to. I used to think that this was his way of saying, “Hey, I’m relaxed in my old age. I no longer need to freak out. I know you’re not going to hurt me.” :]
I have heard that you have to start watching their hips and how they jump and where they jump to. One bad hit to the floor and they could really hurt themselves. We started to give him assistance to make sure that he didn’t hurt himself jumping around because, and we all know cats, they are going to do what they’re going to do no matter what you say. Plus, it’s their instinct to jump around even when/if they are in pain.
We put little step stools around the windows and at the foot of the bed. Sometimes when I saw him about to jump down off the table or the back of the couch, I’d get up and put him down before he’d get the chance. This might be the paranoid me speaking, but it’s because a boss of mine lost a cat after 18 years when she jumped down and hurt her hip really badly. She never fully recovered after that. Two months later, they had to put her to sleep. :]
Schmitty lost a lot of weight FAST when he got sick. And his personality changed as well. Over the last 4 months, he started to hide a bit more and retreat to weird places around our apartment and for an extremely social and needy cat, we knew something was going terribly wrong in the end. I guess look for personality changes. That’s about all I can offer, sadly.
Anyway, I wish I knew more about the older guys. Unfortunately, cancer took Schmitty at the young age of 14. I didn’t expect to have him forever, but somehow I thought he’d live longer than that.
