Their mother is a pedigree ragdoll and the father is a "naughty Tabby" that got into the house.

The girl is the long haired kitten and we called her Foxy.
The boy is shorter haired and we called him Tiger

They are brother and sister, and they are very chirpy, which is really cute.

Hmm maybe I'll try sampling them and posting an mp3.
Here's a video Vimeo
You can here him chirping!
