Rat Snake

Pantherophis obsoletus

The rat snake name covers several North American constrictors, and Pantherophis obsoletus is commonly associated with the western or black rat snake group depending on the taxonomy being used. These snakes are long, muscular climbers that hunt rodents, birds, and eggs around forests, barns, rocky edges, and old buildings. Juveniles are often more patterned than adults, while mature animals in some regions become dark, glossy snakes with pale bellies and strong climbing habits.

In captivity, rat snakes are popular with experienced reptile keepers because captive-bred animals feed readily, reach an impressive size, and tolerate a range of seasonal conditions when housed correctly. Secure lids are essential, as these snakes push and climb with surprising strength. Enclosures should allow both floor movement and elevated perches, with hides placed along a sensible temperature gradient. Wild rat snakes near homes are usually beneficial rodent predators and should be relocated only when safety truly requires it. Breeding records should identify locality or species complex when possible, since the common name is broad.
