Advice needed!!! I have two guinea pigs (Pig and Janice) on fleece. When I change their bedding I always shake it out really well to remove as much hay and hair before I wash it. I always hang it to dry and I?m noticing that there seems to be tiny pieces of hay that seems to be stuck in the fleece and are prickly when I put the ?clean? fleece in their cage. I?m sure it is probably pricking their feet. Any advice on what to do to prevent this? Thank u.
