Honestly, it's no one's business where he is going - that is not the point. The point is that Kitty needs to be rehomed. She is not in danger, he would not let harm come upon her.
I don't think anyone's asked where they're going that they can't take the kitty out of sheer nosiness. I think it was merely concern.

I'd take the kitty but I'm in Arizona and my husband has said no more kitties, as we cannot afford vet bills for additional pets.
