Thank you all for your help with this. I'm still having no luck with any of the food options even after messing with the light and heat. I think I will release it back into the wild in the next day or two as it's nearly spring here on the west coast.I want to try and do the best thing for the snake and it appears to be beyond my aid. Thanks again and perhaps I will try a captive bred garter snake in the near future.

Hope you all have a great weekend,

Heiko
