Does the original owner know of this? Ionno... i dont really think its cool to breed a snake you are caring for, who has a person waiting to get the animal back eventually unless they are okay with it, and know that they will not be compensated for said breedings.
Is it something you have discussed with the owner? Or is this YOUR animal now? Because your previous post seems to me that you are just there caring for it until its original owner is able to take her back, after paying for the food.
Cool that its a female, ive had that happen a couple times now... But just some food for thought on the whole idea of breeding this animal.
