I use a crate on some occasions, like bringing in the groceries and I don't want my little to escape. My Zoe has a bed in every room, but we did need to ban her from the bedroom when both of us are sleeping in the bed. She is very aggressive when hubby moves and tries to bite his hands. This only occurs in the bedroom. When he leaves in the early morning she is allowed to come in and usually will sleep in her bed. I recently purchase a crate for the Care-A-Lot website. It is by the makers of Nylabones. This crate has a see thru top, handles as well a crate wells for your hands. It will fold down flat for storage. Completely washable and the door removes to use as a den. It has plenty of ventilation. This site had it the cheapest around. Plenty of room for blankie, pillows, liners and toys.
