shes not eating

Question
my snake is like three years old she is a corn and lately for the past month she  hasn't been eating  like i put the mouse in front of her and i even use tongs and kind sway it in front of her but its like she doesn't see it  any ideas as to what the problem is

Answer
It is hard to say exactly. Is there any chance that she could be about to lay eggs (ie. has she been with a male)? If not, then you might try varying her food a bit. Offer her a slightly smaller food item. Maybe a fresh killed mouse instead of frozen/thawed. You might also try scenting her food with catfish from the grocery store. If she still won't eat, you might take her to the vet for a fecal test. This will tell if she has any kind of parasite that is affecting her appetite.
