1) I've got four legs, but no tail. (or not much of one )
2) I share my home with a cat.
3) I can speak and whisper.
4) I'm purebred. (not that it matters, of course )
5) I live with my *twin
6) Some of my nicknames are Baby Boy, and Waska
7) My breed is an occupation.
8) I am also 8 years old,
9) 8 years old is quite old for my breed. (meaning, large breed )

Good Luck, I made this one harder
