The alley cats are a group of alley cats who are friends with Mr. Cat.
They all look similar to Mr. Cat and wear the same gloves as him.
- The first one wears a white baseball cap with a picture of a cat's face on it and a white tank top which also has a picture of a cat's face.
- The second one wears a pilot cap with a gold star on it and sunglasses.
- The third one wears a red bandana hat with a skull on it and a dark blue tank top with a picture of a missile on it.
Not much is known about the alley cats except that they like to throw parties, dance, and get drunk, which suggests that they love having fun.
Role in the show
The alley cats often throw "trash parties" at night, with alcohol, dancing, and eating food from trash cans. Mr. Cat frequently attends these parties, a habit which Kaeloo disapproves of.
- Mr. Cat: Mr. Cat is a friend of theirs who often goes to their parties.
- Kaeloo: Kaeloo dislikes Mr. Cat going to the alley cats' parties, partly because drinking and staying up too late is injurious to his health. She tries to insist that the alley cats aren't Mr. Cat's real friends, mainly out of jealousy because she dislikes the idea of her friends having friends other than her whom she does not know. Mr. Cat often talks about Kaeloo to the alley cats when he is drunk, but these conversations happen offscreen so it is unknown what kind of things he tells them.
