I just noticed that the one part that Bob typed looks like a winky frowny face. O.O XD
XD Maybe. I've seen videos of cats playing on tablets. XD
Poor guy.

I've had hip trouble off and on since I was 16. I have no idea why because that was so young. I had it x-rayed once but they said all they saw was spinal arthritis. O.o My hip hurt, not my spine. XD Does he have arthritis pretty bad?
I wouldn't worry yet. Sometimes cats disappear but they usually reappear, especially when they're young. Older tom cats don't always come back. I think they go off looking for females. XD I hope the kitten comes back soon.
Oh, maybe I got scary mixed up with tough. XD Perhaps animals clash with some people like we do? I sure don't like every human. XD
And they won't because humans are flawed and most of them are miserable. But I've talked to you enough to know that you're smart, and I also know that you matter because everyone matters. Plus, you're a good person. *hugs*
That's good.

Just try to ignore the toxic ones. I know that's easier said than done. XD
