Catbert officially entered the strip on March 20, 1995, when Dogbert hired him to the company to handle "the downsizing". Indeed, downsizing is Catbert's greatest joy, and he has numerous binders on this subject (and one that says, "hire losers").
He often abuses workers by doing things like sending Wally home for wearing shorts, even though Wally's pants reach his ankles.
The look for Catbert apparently came from a strip earlier in 1994, where a hairless cat friend of Dogbert showed up at the house. After the cat thanked Dogbert for inviting him over (because hairless cats are usually shunned, he said), Dogbert promptly sprayed him with Hair in a Can, giving him a look that was similar to the eventual look for Catbert.
