Hi everyone! What is the difference between fleece bed spreads and fleece cage liners? I'm getting my new piggie tmrw so I figured 2 piggies is double the poop ��. Right now I'm using towels and that's not really working. Bedding wouldn't either BC I have a giant cage �� So I thought buying a fleece liner would be a good investment �� Now I'm just stuck on the difference. Please help! I don't want to spend all this money and buy the wrong thing!
