This Small Pet Rug is a natural and environmentally friendly play idea for small pets. It is made of 100% flax and is popular with a variety of small pets, especially nest builders like rats, mice, and hamsters. Just cut the mat to the desired size and lay it in the cage. The Small Pet Rug can serve as a sleeping mat, for nest building, or simply as an activity. Animals get the best ideas of what they can do with it. And since it’s made of pure natural fibres, it can be munched on without a worry. It also makes a good bedding layer for injured pets, in order to protect wounds from getting dirty.
