Review on 🐾 Paw Inspired Bamboo Charcoal Guinea Pig Cage Liners: Enhanced Odor Control and Absorbency for Ferrets, Rabbits, Hamsters, and Small Animals by Michele Denzer

They are superior to similar products in terms of moisture and odor protection. For that I give them 5 stars. But I'll mention a few cons I've found with them: For my large cage of 3 guinea pigs I need 5 of these, (again) odor and humidity control, I feel like I could use them for 2-3 weeks. however, after about 1 day the adhesive stops sticking and after about 5 days they start to peel off. If you have a wire bottom cage to put them in and your pet won't walk right on it, I highly recommend it. I'm still impressed with how well it controls odors. However, if your pet walks right on the mat, they may be charged for a larger cage. This brand/option has proven to be way better than others I've tried.
