Bella used it for about the first 6-7 months of her life. After she became potty trained and considered "safe" to be left alone in the house without chewing up everything in sight we put it away. She didn't seem to mind it at all and knew the routine very well. When I would get ready to leave in the morning she would go in automatically. I didn't even need to tell her. She took her cue from when I got my pocketbook. I don't think she minded it, but I guess you would have to ask her really to be sure.

Ripley was crated for the first few days after we got him. He cried and cried which told me he had probably never been crated before. I couldn't stand him crying at night so I let him sleep on my bed and just hoped that he was housebroken, and as it turns out he was. After a few days of being crated while I was at work I got brave and decided to leave him alone loose in the house with Bella. Fortunately when I came home all was OK. For me crates were only a temporary tool.
