I have similar issues with our cats.  My bf's cat always bullies my cat.  However, whenever I give my cat catnip it tends to toughen him up for some reason.  Or he just becomes more expressive.  He's a pretty laid back cat, and doesn't really let anything or anyone get to him, not even the dogs.  He sometimes gets perceived as being a wussy, but I see him as classy, sophiticated and low-key.  My bf's cat is always so needy.  Don't get me wrong, I love him to pieces, but he tries to run the other cats off whenever they go near us.  His name is Rowdy and it fits him perfect.

Are you missing the younger "bully" cat? I found one in my garage this morning. He could be 3 years old. Blue eyes, brown and black,with a white "milk" mustache.

I have a suggestion for you about the bullying though, in case this cat is not yours. Get a Bigger Cat to kick his butt! LOL

You'd think the 2 dogs would put him in his place.  Nope.  In fact, he sleeps with the dogs.
