I would suggest that since you only have one unneutered male to get him fixed with the early bunch going to the vet. At least that will buy you some time without more kittens. Another priority would be Ms B since she seems to be an escape artist. Then if the others are inside and not around intact males, there shouldn't be more kittens. Thank you for all that you are doing to help these kitties. I know how hard it can be. I have 6 at my house right now that showed up as strays and that I've had fixed and vaccinated, along with other vet treatments. In the last 2 weeks, three more have been seen eating out back. I will try to help you in a small way if you post the address of the vet's office to have the male cat fixed.
