about a month ago me and my nieghbor gaught a huge garter. it is the biggest i have ever seen. we put her in a plastic shoe box about 30 gallons. she is doing great. she eats worms, toads, and we even got her to eat a pinkie. the only thing is she is really agressive. bellow the stomach and before the tail is a bulge. could this mean she is going to give birth. if so when do garters have babies. thank and please help.
