Yeah, Cairo will do the same to a blanket in there if he can't get the door open. He hardly ever goes in the baby cage more than a couple times a week, no more than ten minutes at a time.
This probably won't help, but Deke is really short for Zindeku it means "protective charm" in swahili. Thats not his registered name. His name describes his personallity now, but not when he was a puppy. He grew into it.
