Garfield is a comic strip created by Jim Davis. Published since June 19, 1978, it chronicles the life of the title character, the cat Garfield; his owner, Jon Arbuckle; and Arbuckle's dog, Odie.
Roger claims his red wig in "Old Stan in the Mountain" looks like Garfield had a miscarriage.
Garfield is mentioned several times as the characters try to separate the cat from former President James A. Garfield in "Garfield and Friends". The episode title also references a television series about the cat.
Hayley recalls ordering a Garfield doormat that failed to show up in the mail in "Fight and Flight". When she believes a package for Klaus was misdelivered to the south extension of the street, she suggests they try there. The owner denies having Klaus' shoes, but when Hayley spies the missing doormat that she ordered, they burst in with guns drawn and hold the owner hostage. Hayley later gets a call from Jeff telling her that Klaus' package was in the bushes at the house and she also admits that perhaps she didn't really buy the doormat either.
