I know that my garters would certainly attempt to eat my cats...lol. But a garter eating a cat successfully? Ummm...maybe according to Billy the Exterminator...lol. I'm sure if he saw a garter on his show, he would call it a vicious, venomous snake and recommend that he and his stupid brother remove the snake immediately for everyone's safety. The biggest garters I have seen around here are about 4 feet long...easterns. Sometimes, I have to admit, I wish garters could swallow people. There would be quite a few people on my list to feed to my snakes...rofl.
