Murphy has a pet Cat named Charlie because he or she (nobody knows except maybe the Vet) has a Charlie Chaplin (not you know who) mustache. They found each other very early one morning after Murphy was done with his tooth fairy shift. They rushed towards each other and Murphy picked Charlie up and took Charlie home to his small apartment.
After pretty much just going to bed, Murphy used all of his money in his wallet to get some cat food, a litter box and litter, then put some ads out about a found cat. He got one response, bu it was the wrong cat, so he kept Charlie.
Charlie gladly comes to anyone that visits to get petted, and is like most cats, except Charlie like broccoli, getting in the tub, and getting walked like a dog. You don't expect a pet of Murphy's to be perfectly normal, do you?
