Pituophis catenifer
A large North American colubrid with big dark blotches over a sandy brown ground. Adults are 91-213 cm and heavy-bodied, and when threatened they inflate the body and vibrate the tail in imitation of a rattlesnake.
Pituophis catenifer is a large colubrid found widely across North America, with nine subspecies currently recognised. Large dark brown to black blotches run along a yellowish to sandy brown ground, with smaller spots on the flanks. Adults are 91-213 cm and heavy-bodied. When threatened it inflates its body, flattens the head into a triangle and rattles its tail against the ground, so it is often mistaken for a rattlesnake, but it has no rattle and is non-venomous. An epiglottal keel in the throat lets it produce a remarkably loud hiss. It is diurnal, inquisitive and given to burrowing. In captivity it has a voracious appetite, so overfeeding must be avoided.

Frozen-thawed mice and rats
Provide a thermal gradient so the snake can choose where to sit. It prefers relatively dry conditions and needs no added humidity outside the shed cycle; when a shed approaches, offer a hide filled with damp moss or paper towel.
Active and an accomplished escape artist, so the enclosure must lock securely. Floor space matters more than height: an adult does best in an enclosure about 120 cm long. Because it burrows, use a deep substrate and provide hides.
Hatchlings take mice and adults take rats. Offer prey the same size as, or slightly larger than, the thickest part of the body, once a week. The appetite is voracious, so guard against obesity from overfeeding; thawed frozen prey is the safest option.
Most individuals are docile and handle well, though some put on a loud defensive display. Bites are uncommon, but hatchlings can be nippy and settle with regular, gentle handling.
Not listed on any CITES appendix, and not among Japan's designated dangerous animals. It is non-venomous but grows large, so secure the enclosure carefully and take care when feeding.
