Hello, currently we use kaytee paper shavings for our guinea pigs potties but as we now have 5 pigs instead of 2 it's going to be very expensive. When we got our 3 new pigs from the spca they were all using wood pellets in their potties and they told us how inexpensive they are. We also have 1 Peruvian guinea pig and she drags the paper shavings alllll over the cage. So with them being cheaper and less messy I'm thinking they might be a great option. The one concern I have is whether or not the pigs will try to eat the wood pellets. This would be very bad as when they get wet they expand and that could hurt the pigs stomachs. I was just wondering if anyone has any experience with these and would be able to tell me if they are a safe option or not. Thanks!
