[SIZE=1]Glass aquariums are acceptable, but do not offer the same ventilation as a wire cage, so must be cleaned more often to avoid harmful ammonia buildup. A cage should offer a bare minimum of 2 cubic feet for one to two rats -- about the equivalent of a 20-gallon long aquarium, but more room is always better. I prefer 2 cubic feet per rat. I always recommend that people purchase or construct the largest cage they can. [/SIZE]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=1]Wire cages (such as rabbit and ferret cages) are by far preferred. They offer superior ventilation, plenty of climbing opportunities, and better flexibility for modification and "decorating." Space between wires should be between 1/2" x 1/2" (for babies) and 1" x 2" for adults.[/SIZE][/FONT]

Cage—A rat cage should be at least 12" by 24" but buy the largest cage you can. You can choose from wire cages or aquariums, or a combination of the two, stacked or joined with tubes.

Clearly i do my research and i find it unsettling people are accusing me otherwise. I'm not a bad pet owner or in experienced im going to college to be a vet right now at the moment so i am very well versed in the animal care. Not to mention my whole life i grew up on a petting zoo and we always had small pets as well as large.
