Naturally Fresh Cat Litter - Walnut-Based Quick-Clumping Kitty Litter, Unscented , 26 lb

We have the 4 trays on our 2 macaw bird cages set up like litter boxes. This works great, traps their nasty morning poop smell, is easy to clean usong a scoop and I dont worry if the birds ingest a bit from the top cage trays.
