I just googled "How to calm a hyper cat" and THIS old post that I did came up from years ago!!! I completely forgot about this! I read the responses, which were great.
Things got a bit better for a while- or perhaps I just adjusted. But things are a bit crazy again. To respond to those below, Oliver isn't afraid of the dark, I play laser light with him and feed him until he is about to pop. When I put him in the bathroom so I can sleep, he runs at the door full speed- FOR HOURS. My boyfriend has recently moved in with his cat and I am slowly introducing Oliver and Bean to it. But Oliver is now keeping us both up. I think I need to do the one thing on here I haven't tried- ask the vet for some sort of sedative for night time. It's just really outrageous. While I am at work, he sleeps, so I can't keep him up all day. When he isn't going crazy, he is very loving to me.
Thanks, everyone!
