Cage – Minimum of a 1’ x 3’ enclosure with a secure top for each pet. Cage bottom should be solid, as screen mesh/wire can irritate the feet.
Substrate – Bedding should consist of a paper pulp product (like Carefresh or Yesterday’s News), newspaper or computer paper. Wood chips/shavings are not recommended.
Hide box – Hiding areas such as cardboard boxes, paper towel rolls, and tissue boxes should be provided.
Cagemates – House rats as individuals or in same sex pairs/small groups. Monitor closely for fighting, and separate if necessary. Spaying or neutering may be worthwhile in certain situations, as it allows for mixed gender social groups, and may reduce the chance of mammary tumors. Rats kept individually should be handled daily.
