Hello everyone Lian here. I am pretty new to piggie care, right now I have two little girls and there set up is temporary. They have a fleece pad and on top of it is a towel. I noticed it seems like they might be getting chilly at night, the towel is laid flat so it doesn't offer much snuggle-ness. I wanted to give my piggies an old pair of pajama pants but hesitated because I thought they might be able to hurt themselves somehow by crawling inside or what not. Please let me know what you think, and what would an experiences owner do to help offer your piggies a little warmth? Thanks.
