I am offering mine small raw bones, chicken, beef and pork, all organic raised by me or neighbors plus wood and mesquite beans in the shell for chewing/boredom. Mine all have wheels, too. I have mine in racks made from lowes concrete tubs, but they have some there that are much more sturdy and we are contemplating making a rack for those. Those tougher tubs are also taller and might be better since these guys do jump when scared or mad I have had mine for about 2 months now. All 3 of my older girls are FAT FAT
