I believe Wonton is happy, but I worry sometimes that he's bored
He has lots of toys, and I play with him at least twice daily, for 30 mins each time... some days more than that, but that's the minimum. He doesn't meow at doors, but sometimes if we open them he tries to get out. Sometimes he just sits there though. He likes to sit in the window and look at the birds in the backyard. I just worry that he's getting enough stimulation...
I've tried taking him for walks on a harness... maybe I should start that again. I tried walking him in the front yard/down the sidewalk, but everytime a car went by he'd get scared and try to run, so that doesn't work. I took him in the backyard a few times on his harness, and he liked it, but he'd growl when I went to pick him up. It didn't even seem like he was growling at me, but it made me nervous, so I stopped doing it. He has lots of toys and his cat tree... I just hate to think he's bored here, or depressed cos there's nothing to do. He snuggles with us constantly though, and purrs lots, and is always so happy to see us he headbutts us and even leaps into our arms, so I guess he's ok. I just want him to have a good life. I rescued him, so he's my responsibility now - I want to do right by him.
About Stumpy - I do think part of it is her age - she's just not settled down yet.. I think she may just need time.. but I do think you should try to figure out some way to keep her from jumping on the mantelpiece, if there's a chance it could come down. I know easier said than done.. I've catproofed in here quite a bit. I cut the strings on all the blinds so Wonton couldn't get his head caught in them and choke.. thankfully he doesn't chew on wires, but he loves to investigate small places, and a few I've had to block off so he won't go in there and get stuck.
Have you considered medication? It might seem extreme, but it really does help some cats. Wonton is much calmer now that he's been on Prozac for a while - life is better, and both the cat, and my bf and I, are happier
