AW, this brings back memories. Grandma was just about that age and pregnant when someone dropped her off at my house. I never even considered aborting the babies.

She did fine and loved her babies a lot. She only had three but sometimes the first litter is a small litter. I stayed with her while she had them in case she needed help. She had them in a cardboard box on my porch. She didn't need any help but was sure proud of them. After one popped out, she would clean it up and look at me and I swear, she would smile like "look what I did".

I'd say let her have them and raise them until they were old enough to go to good homes.
