Dogs & cats are well-represented, but I'm a rabbit person and would love to know if there are any series with a rabbit in them. Thanks!

Wendy Roberts character Sadie Novak in the Ghost Dusters series has a pet bunny named Hairy.  Hairy is around for all the books but he doesn't really figure into the mystery.

That's all I've got right now.

The only ones I can think of are the Harmony series by Jayne Castle, but the pet dustbunnies aren't exactly rabbits.  It's a light paranormal mystery series set on the planet Harmony, which was settled by humans.  No sci-fi type stuff though.

"The Cottage Tales of Beatrix Potter" by Susan Witting Albert have some bunnies in them.  You might like this series because there are a variety of animals who talk to each other and help Beatrix solve the various mysteries in the book.  Badgers, owls, ferretts, dogs, cats, rabbits, snakes, ducks, sheep, cows..............

Thanks! I'll give these all a looksee. :-)
