A break through in small animal pan design! Heavy duty, rustproof ABS plastic pan construction that virtually eliminates the shipping damage that plague metal pans. Easy cleanup, no corrosion, less calcium buildup, and lighter weight. Lasts far longer than conventional metal pans. (Note: The ABS pans are tapered and slightly under the size listed allowing them to slide in under the cages.) ******* Please note the DP8-P 36 x 24 plastic pan will NOT work on Ferret or Critter Nation cages.
