I have been feeding my garter snake baby and and medium sized mice. Recently she has stopped eating. She recently shed within the last month and ate one or two since then. But now she had let three meals go to waste. I have always sliced the mouse open to get the smell to float around in her cage but now she just smells and ignores it. I added more humidity and heat but nothing is making her eat. I don't know what to do and I am getting worried reading posted about tapeworms and mouth rot. Please help.
