Junior Guinea Pig
My two Guinea pigs live in the garage in a hutch. During the winter they have had a night time box full of hay to sleep in and a fleecy cosy or plastic hut thing full of hay during the day - result = hay EVERYWHERE in the house as its walked around 
Also it needs changing every day as the bottom gets wet from wee.
I started giving them the boxes full of hay mid autumn so they were warm - now its obviously getting warmer again would just another fleecy cosy be ok - I would get another one that fits two. Would that be ok?

They should be fine in just a cosy, but boxes full of hay give them something to play in as well. So maybe give them hay boxes every now and then?
