My Mama's Boo was lease trained but they just put her outside the patio doors on one, didn't walk her on it or anything.

Chesters kennel has a place for wheels but I wouldn't use it to take him out for walks.. It is just a heavy kennel and he is a heavy cat and everytime I take him to the vet, I wish I had the wheels for it! Put two of my baies in there and try to carry it is a JOKE... it is more like dragging it!
