I have one jungle carpet python that is just giving me a headache for not accepting rats.
I have talked to Will Leary and a bunch of other hardcore snake people and I guess there's
1. Washing the F/T rat
2. Scenting the F/T rat with mice an mouse litter
3. Trying a live rat
Etc.. Etc..
I am going to try a new approach since the other haven't worked for me yet. I'm going to let a F/T rat sit in a bag with F/T thawed mice for at least twelve hours and maybe even mix room tempiture water in to get there scents mixed together then offer the rat.
Anyways,It's a learning experience!
Good luck!
