I'm a big fan of murder mysteries, especially the "cozy" type. I really enjoy the ones that have pets as characters, especially cats.
My mom introduced me to Lilian Jackson Braun's
"The Cat Who..." series with the two Siamese cats.
I also discovered:
Carol Nelson Douglas
and Midnight Louie
Shirley Rousseau Murphy
and Joe Grey
Rita Mae Brown
(and Sneaky Pie Brown) and Mrs Murphy
These mostly feature cats but Mrs Murphy has a Corgi pal.
I also recently discovered Susan Conant
and her Alaskan Malamute buddies. I'm more of a cat person but I enjoyed reading about her characters' lives with their dogs.
A while back I read another mystery where the main pet characters were Poodles but I can't remember the title or author...
also writes cool novels with animal characters in them - mostly horses and a rather cool coyote. Not quite mysteries but a lot of action in them and even a ghost or too (I don't like ghost stories per se but I didn't mind these ghosts lol).
I'm always up for new reading material -- can anyone recommend any more cozy pet mysteries?
