Texas Rat Snake
Non-Venomous
Average Size: 42 to 72 inches
The Texas Rat Snake has a voracious appetite, consuming large amounts of rodents and birds, and sometimes lizards and frogs which they subdue with constriction. They are generalists, found in a wide range of habitats from swamps, to forests to grasslands, even in urban areas. They are agile climbers, able to reach bird nests with relative ease. They are often found around farmland, and will sometimes consume fledgeling chickens and eggs, which leads them to be erroneously called the chicken snake. They are known for their attitude, and will typically bite if handled, though their bite is harmless.
rat snakes are large, powerful constrictors that consume rodents like a kid would candy! It is not uncommon for several mice to be constricted at one time by a Texas Rat while another is currently being eaten.Texas rat snakes have a reputation for being one of the nastiest of the rat snakes.
