I do not understand why all these people are telling you to feed your snake a variety of food. A variety is only needed IF your snake is not eating pinkies. Mice have all the nutrients your snake needs to be healthy. If you are feeding your snake worms, fish, or anything else you need to feed a variety. The best thing you can do is get your snake back on pinkies and quit feeding the worms. Most garters will take worms over pinkies more readily because that is what they eat in the wild and what they recognize as food, so feeding worms sometimes makes your snake not want the pinkies. I have had garters for years and this is the best food for them. Good luck with your new snake, garters are great snakes to have as pets!
