Pocket gophers feed primarily on the taproot and often kill plants. Their feeding can lead to significant yield reduction, and their burrows cause damage to harvest machinery. The name pocket gopher refers to the fur-lined external cheek pouches, or pockets, used to carry food and nesting materials. The pocket gopher can close its lips behind its four large incisor teeth, keeping soil out of its mouth while burrowing.
Pocket gophers use their short whiskers and tails to help navigate tunnels.
They have a keen sense of smell, which they use to locate food. Pocket gophers do not hibernate and can be active in the snow. They are more active in the spring and fall than they are during the heat of summer. The female usually produces one or two litters per year but may produce up to three litters. Average litter size is 5 or 6 young.
