Model C306 is a revolutionary accessory designed to make feral cat care as stress free as possible. This accessory slides into the rear door slides of a transfer cage and feral cat trap allowing you to use your transfer cage as a litter box cage. Coupled with our new disposable litter tray this accessory will make long term cat care and recovery safer and healthier for feral cats and you. Use a trap divider to section off the cat in the trap then remove the sliding doors from both the trap and transfer cage. Insert a disposable litter tray into the transfer cage. Next line up the cage and trap then simply slide the connection piece in place. Now that the connection piece is in place remove the trap divider so the cat has free reign of the trap and litter box cage. This product works with model 306, 306NC and 306NC2 transfer cages, 306SQ, 306NCSQ and 306NC2SQ squeeze cages and trap models 606NC, 608NC and 608FN. A separate connection piece is also available to connect multiple cages together model C307. With both model C307 cage to cage connector and C306 trap to cage connector the possibilities are endless.
