My six foot long grey ratsnake has now gone over six weeks without eating. She usually eats one mouse a week. Her tank is a bit on the cool side, as the weather is a bit cooler (and it's a glass tank), but this has not bothered her before. She has shed once during this period, and her eys are clouded like she is going to shed again. She seems to be drinking but is not very active (but she can be quite lazy anyway!) I've pinched her skin and she does not appear dehydrated and seems otherwise well, any ideas? Or should i stop worrying?!
