EZ Whelp Fab System Whelping Box Add-On Room

This is NOT a complete whelping box. Rather this can be added onto the EZ Whelp Fab System Whelping Box, to create a second room to help housetrain pups and to give your pups more play space. Multiple rooms can be used together to create separate spaces for play, feeding, and potty areas, or to separate the puppies. 3' x 3' can ONLY be used on the 3' x 3 box, but 4' x 4' and 6' x 4' boxes and rooms are interchangeable.

NOT A STOCK ITEM. OVERSIZE.

(whelping box, pads, and heating system not included.)
