Garter Snakes are a greenish-brown to black with two bright stripes running down their backs. These stripes can be bright yellow or light green. Sometimes there is a third stripe between the other two stripes, which can range from red to green. Their bellies are a slightly lighter version of their back color. Garter Snakes can be about 15 to 26 inches long. Garter Snakes are silent, and do not even make a hissing sound.
Garter Snakes can live in a wide variety of habitats, including meadows, rocky slopes in the mountains and brushy thickets in cities. They prefer being near water. Garter Snakes use dens for resting during the warm months, and hibernating during the cold, winter months. Their dens can be spaces under logs or rocks, or previously used animal burrows. Snakes will share a den during hibernation and use the same den for many years.
Garter Snakes are born in the summer and early fall. Young Garter Snakes are born alive, meaning they don't come from eggs. There are usually 10 to 18 in a litter, but the number can be higher.
Garter Snakes eat eggs, mice, voles, slugs, bugs, frogs, fish, snails and lizards. Young Garter Snakes primarily eat earthworms. They need fresh water for drinking and find much of their food near natural water sources.
Garter Snakes are usually brought to PAWS after they have been attacked by pet cats. Occasionally a snake is brought to PAWS who has been injured by a lawn mower. PAWS gives the snakes medical care to help them get better and then releases them back into the wild.
