Degus love it
I use these mats in the bottom of my degus' cage to protect their feet from the wire floor. They are nice and thick - it takes my super destructive degus a long time to get them noticeably shredded - and very absorbent, even under a leaky water bottle. My only slight concern is a little bit of dust formed of tiny fibres produced when the matting is chewed up, though I only notice it when picking up the shredded mats while cleaning out and the degus are certainly happy and healthy.
Great for degus or any metal grid cages
I've bought this from zooplus for over 7 years for my degus multi level cage and it's great! It covers the mesh perfectly and they've never had any foot problems because of this! They can tear it up a bit into a fluffy nest as required but it's generally long lasting
