Can anyone give me a website where i could get a pull out litter tray cage for a guinea pig?

I have been on the search for the perfect cage for my two chinchillas and have found that the Prevue Chinchilla Ferret Guinea Pig Cage is definitely the best choice for your pet guinea pig.

This cage is available in a dark red hammertone finish. The large front door and smaller rooftop door allow for easy access to pets. The pull-out bottom grille and tray make cleaning quick and easy. The wind-bell lock, on the bottom of the cage, prevents pets from pushing out the tray if the cage is used without the grille. A bottom shelf is also included for storing extra food, treats and supplies. The dimensions are 31"L x 20 1/2"W x 40"H (interior cage height is 28 1/4") with 3/8" wire spacing.
