My red sided garter eats almost anything, I feed her once a week on fuzzies (slighty bigger mice than pinkys) and occasionally give her worms and and slugs between her main feeds, she is in great shape so far being about 6-7 years old now her diet has not let me down.
I don't like to go overboard on slugs as I find they tend to slime up her mouth and face.
I also slip in rabbit kidneys and hearts when I manage to shoot one, but thats mainly in the spring and summer.
