Squidgy is a free range house bun, with a 4' double hutch as his 'base'. He usually lives on blamkets anyway, but after his neuter, we took the ramp out so he couldn't get upstairs, and shut him into the bottom part of the hutch. He was very groggy anyway. We popped a hot water bottle, covered in a blanket in there for him, which he really liked. We kept him in there overnight, and then let him free range, as it stressed him quite a lot keeping him locked up. We still kept his stairs blocked off though.
