This is my little Mutt Ragdoll Angora ferret Bindi and my little cinnamon girl Suri play wrastling. Bindi is tiny, but she is mighty, won't back down at anything. Suri is a little sweetheart, she doesn't like to wrastle, but she will with Bindi. The sound you hear is a dooking sound ferrets make when either excited or upset, depends on the situation. That is Suri you hear mostly. Suri is a rescue from Texas Ferret Lovers Rescue in Balch Springs, TX. Bindi came to us from Carolina Ferrets out of North Carolina. She was an expensive Christmas present for my husband and I back in 2006. (less info)
