Cats are known to do strange things and misbehave when they have some emotional issues. They’re just trying to tell you something is wrong. The fact that the new kitty sleeps in the bed makes is really appear that the new cat has a high place of position in the family and would sure affect the way Cho feels.
I must agree with the former reply about cats needing to be indoors. There are too many awful stories out there and with all the “new” diseases going around, it’s certainly not healthy for the cat or others you have in the household that don’t go out.
You might want to post this on the PETS section since Critters is more about wildlife, bugs, etc. :)
I’m so glad to see you looking for answers rather than just “getting rid of” the cat. He wouldn’t be acting this way if he didn’t love you so he’s only trying to tell you something is wrong.
