Debbie,

If it comes to living outside vs being killed, I'd go for living outside (possibly being sheltered in a garage or something in the winter).

As far as the Siamese mama is concerned, here's a link to a Meezer Rescue in your area. Contact them IMMEDIATELY and tell them the meezer is there and is in danger of being killed. They'll pull her out before she's killed.

Good luck and keep us posted.
