Junior Guinea Pig
Panicking. I noticed some weird patch of hay in the pigs' cage and when I picked it up it was all stuck together and partially white, with white spots. My brain thought maybe they did a calcium pee on it but it was completely dry. I broke it up a bit and a bunch of dust came off of it. That clump of hay was not there before and none of my bags of hay seem mouldy (about to check them again) but I don't want to risk the piggies getting sick from mould. What should I do?
