Where can I get mail-order cages and supplies cheap?

Tom had found the Morton Jones Co. (MJC) in San Diego (800-443-5769) or (619-789-1544) to have the best prices and selection of cages, bottles, drugs, etc. They have a very informative free catalog. They will also make custom cages to order. They have a "LesRoss"-style 3-bay rat cage available. Not listed in catalog. It is optimized for rats and has a deep pan. Sheet metal wheels have proved popular with those who like wheels for rats. Call Leo at Fern Manufacturing at (818) 365-2615. He invented these wheels and had several of us test them for him. They truly are the best wheels available_also very reasonable. Leo also makes fantastic cages set in plastic cat pans. They are also powder-coated for easy cleaning.
