Would a opposum hurt baby kittens? It's a large opposum and it probably is coming for food where the baby kittens are they are about 7 or so weeks old, and the mother is very small, I don't have any idea if it would be trying to hurt them. I am in the process of trying to get mommy and kittens out of there, just can't figure out who to get first, the mommy will not have any part of a trap or carrier, I can pick her up so I am hopeing I can get her in a carrier quickly, but I don't want the babies running off and hiding...
