So I've had my pigs on pine wood shavings for two years. And my parents are tight gits and don't want to change because we get the wood shavings free. I've noticed their feet being extra red and I know it the wood shavings fault, and I can't just lay hay on the floor because last time I started doing that, my guinea pig got a hay seed in his eye and it cost us £60 for treatment and consultation! My dad says he doesn't want their wee and stuff in the washing machine and I can almost see why. When I mention cloth bags he says the dirty animal water still gets through, how can I solve this problem and how else can I convince him to start using fleece?
