Cats that retrieve are a hoot. I call them "fetch kitties."

If you have a cat with a strong retrieving drive, they'll go past when a labrador retriever will stop and take a nap.

Be very, very careful with the hair elastics and rubber bands. They are very common causes of foreign body obstructions in the GI tract of cats. One of my patients died after the surgical specialist removed bits of them in eleven places in her small intestine.

It's strange what cats like. My SIL's fetchy kitty prefers pieces of paper rolled up into balls. One of my cats liked Brill-O pads.
