Jon has used leashes on Garfield during early strips, which Garfield detested. He tried impressing women with Garfield on a leash on an August 26, 1979 strip, but it failed. Finally, on June 27, 1981, he had come to realize that leashes were not right for cats.
First leash appearance August 1978
- Even though Jon promised Garfield that he wouldn't use a leash on him again, he made him wear one 6 years later on an October 5, 1986 strip.
