Why can't she "sell" you her animals and anything else that she thinks the husband may take just to be spiteful? Document a bill of sale or something to show that you now legally own the stuff and since it is no longer owned by her or her husband, he can't ask for them in the divorce. Then once everything is finalized, "sell" them back to her.
I don't know if this would work but I would look into it.
