I don't know what's going on. my snake was fine with f/t for 3 years until about a month and a half ago. I have gone through 3 rats now. The first 2 she attacked and strangled, but didn't eat. The last one I tried to feed her, she didn't even bother attacking. She eyeballed it as if she was hungry, got the "attack" stance...then turned away.

I feed her in a cardboard box, the same box i always use to feed her. Now and then i swap it for another that is the same shape and size.

should I move on to live bait? thats the only option i see right now.
