Hey there Joy, Your snake is not a baby she's most likely an adult or sub-adult. Female garters are alot larger then their male counterparts. In regards to feeding, I have had garters refuse dead fish for awhile then not have a problem with it at all. I have also had them refuse trout strips but luv salmon strips ... I think it best to try and experiment with different things and perhaps change it up from time to time. I was recently surprised when canned salmon was a HUGE success. I now stock a few cans of salmon right beside the dog & cat food cans ....

Best,
