been done.
the webcomic Kevin & Kell sent Lindesfarne the hedgehog into orbit back in July 2000.
For those who haven't been following the (drumroll, please) longest running continuously updated webcomic still around, Kevin is a rabbit. Kell is a wolf. They're married. (Yes, really. Kevin's a really big rabbit.) Lindesfarne is their adopted daughter. She's really British royalty, but can't stand the taste of English food. (Yes, really. She had her big ears trimmed.) There's more, but the strip's been running every day since September 1995 and has had MANY story arcs. if you don't like predator/prey jokes, stay away. If you don't like puns, particularly predator/prey puns, stay away. http://www.kevinandkell.com/about/ leaves a lot of stuff out.
