Guinea pigs have sensitive feet and spend most of their time on the cage floor, making the choice of liner crucial for their comfort and health. Unlike wire-bottom cages, fleece liners provide a soft, absorbent surface that prevents bumblefoot and keeps your pig dry. Our editorial team researched popular fleece liners to find options that balance absorbency, odor control, and easy cleaning for guinea pig owners.

We focused on liners with multiple layers (fleece top, absorbent core, waterproof bottom) and considered guinea pigs’ natural digging and burrowing behaviors. We also looked at fit for common cage sizes like 2×4 C&C grids, since guinea pigs need ample space. Here are our top picks for keeping your cavy cozy.
