Izzy will be two on 12/29 and she still uses her crate but not for sleeping at night because that girl is in our bed.
But she uses it as her safe place to hang out when she can't crawl into our laps..lol.
or when she just wants to rest and take a break she will sleep in it. I always have it open with her comfy bed and water bowl.
Also if I'm going away for just an hour or two she goes in there. She is never left free in the house..not with those crazy cats of ours.
