This is a Kawaii ceramic hay feeder. Recommended for rabbits, degus, and guinea pigs that like to chew. I put it in the cage once, but my pet didn't seem to like it, so I'm selling it almost unused. Since it's ceramic, it's easy to wash and sterilize with boiling water. It comes with two wood screws so you can fix it to the cage. If you use the steel mesh divider, you can put both hay and pellets in it. If your pet plays with the steel mesh, you can remove the mesh. Thank you. Comes with a sample pellet as a bonus.
