You know matt would it hurt you try being positive and not looking at the worst possible outcome of something. Shes more interested in the concept of being a mother then in having lots of babies.
The Problem Coker is that well, she need to learn that she can't follow such wish without her owner's agreement, and if he doesn't agree, she should lay down, if she's a good gold badge or platinum she will understand, if she's a fake one...well...castration is your best friend to make your pets avoid uncalled for births.
Coker, it's a pet, don't feel sad, it's part of the pet nature, their opinion doesn't matter much for an obvious reason, in the end, the one paying the bills, the food, the mister bed, the mister house, etc. is the owner, so he or she has the word about if their pets should "refresh" or not, because for what the yukkuris cares in general, they refresh and then, Expect the owner to take care of the babies as well without caring about the owner's capacity of taking care of them or if he or she wants to begin with. It could be worse, she refreshes, and guess what? Gruesome death or being kicked out and live the life of a gutter trash, compared to that, castration Isn't sad at all, regardless of her wishes at being a mother, at least she'll have an averagely good life and if things go well and the owner can a Partner that ,while they may not have kids, at least they'll have each other.
Easily, better than fulfilling that Wish without considering the situation of the owner's place and facing the consequences of that.
So? you remember we are talking about yukkuris, right? you know like, everybody likes to be dicks on them or make things more painful for them for no apparent reason or for very darn good reasons, it doesn't change much that she clearly is getting neutered and there is no problem with that, no sad moment, only a typical pet moment, but this time it's a pet yukkuri which has t's own world quirks and aspects that make it a bit different from the average neutering.
