He passes a rat that has fleas and the fleas are attracted to Catdog. Now,the fleas have made a civilization on Catdog. They decide to go to the doctor and he offers them a special flea bath that could cure them right away, but Cat refuses. The doctor says that the only other alternative is a flea collar. They wear one for a while and everything seems ok, but of course something happens and it all goes downhill. Cat finds out that flea collars are "out" this year and refuses to wear it. He forces it on Dog, and without protection Cat is quickly covered in fleas. They begin to fight over who has the right to wear the collar, and by the end of the fight, they had rendered it useless. Cat finally gives in and they take the special flea bath anyways.

CatDog become celebrities and fame goes to Cat's head. He starts eating too much and insulting Dog. His cockiness gets the best of him when he accidentally insults Rancid Rabbit, causing the whole deal to crumble before his eyes. Cat decides never to let fame get to him again.
