All I can offer are prayers that all things fall into place and Mama
and babies can both be helped. This reminds me of how I became a cat
owner. Helping a stray Mama cat. She had her babies outside, but brought
them (6 babys) into my garage shortly afterwards. (where I was feeding
mama cat) With the help of my old Vet, got them all fixed,shots & placed
for adoption except the last two, who I kept myself. The Vet was a Saint
and gave me a deep discount for their care.

Best of luck with this mama.
