I have our rabbit, who normally stays outside in a run, in the house while it's hot during the hottest part of the day. Only thing is she has to stay in a cage (dh doesn't want any animals in the house so it's a big accomplishment even having her inside). I tried those cage liners but she just scratches them into a big wad. I don't have enough old towels to use those every day. I have equine pine and I can shred newspaper. Would either of those work? I'd rather not use straw because I don't want to bring bugs in the house in it.
