I use carefresh paper bedding and have been for a year. My piggy has been recovering from a URI over the past two weeks, and just the other day I noticed her nibbling on her bedding. I've never noticed this before. She still doesn't quite have her appetite back. She'll nibble on carrots, but hasn't shown interest in pellets or hay. I've been syringe feeding critical care. Any advice on why she's doing this? And is it harmful? Thank you in advance!
