Anyone else here have ferrets?

Hey y’all I just a 3 month old ferret on Saturday. I bought him two hammocks, one he used the first night he was here with me and the other he attempted to get in but needed a little help. I ended up taking them out since I was sleeping and he was trying to play with them and kept pulling on them. I tried putting the one he seemed to like back in but he’s been choosing to either make himself a little bed on the bottom of the cage with the puppy pads or using the puppy pads as a blanket. Is there some kind of small animal sleep sack I can buy?
