We live in a cold house and temperature has dropped here a lot in the last week. The guinea pigs don't seem cosy enough to me in their indoor run so i bought a little cushion to put underneath their igloo. It's one of these - sort of faux sheepskin on one side, fabric on the other with a thin cushion inside. The cover is washable.

It is actually a dog cushion. I put it on for a trial run and they seem to like it.
Anyone know if it is ok to use this type of thing in the run? We have stuck to newspaper and hay so far.
