This whole situation is so sad. Are there any rescue groups or TNR groups that can help out with spaying and neutering of these cats? Are there any vets in your area that offer low cost spaying & neutering? Some vets will do this especially for feral cat colonies. Many people say they will fix their cats and then things come up and they never get around to it and then more kittens are born. I hope that all of the kittens and the mother cat will be able to be fixed asap and that something can be done about the other cats that keep on having kittens.
