Review on Penn Plax Biodegradable Litter Liner Cats by Sara Bertrand

We've been using these lignin-based litter liners for our cats and are extremely pleased with the results. They are easy to use and fit perfectly in our litter box .They are also biodegradable and environmentally-friendly, making us feel great about our pet supplies choices. The only downside is that they aren't as durable as traditional plastic liners, so they need to be replaced more often. Overall, we highly recommend these liners based on our own experience..
