Mil called me, apparently dh called her to vent about BM. Mil has an old 10 gallon tank she will bring over. We still have nothing else but at least I can get this gecko out of this box.
As for sd, she and I sat down. I explained to her that it wasn't right of her mom to assume we were ok with this, and that BM should have either spoken with us first, or not bought it at all. I reminded sd that we don't have small pets for a reason, that they are work, but if she wants to keep it, she has a decision to make, it either goes back to her moms house and her mom can provide the rest of the essentials, or sd will have to use some of her allowance money to help with the costs, and if she wants to keep it here, she has to fully take care of it, that means feeding it, watering, cleaning the tank, all of it. Only reason I said she will have to help with costs is because she knew her dad and mines stance on pets in the house. We have a cat, who I've had since before dh and I met, and I still have to take care of the cat, buying her food, changing her litter box, and socializing with her, she is my responsibility, and this gecko is going to be sd responsilibilty. I told her to think on it until grandma and her dad gets home before she makes any choices.
