Hi Maryann Mendoza, thank you very much for your kindness in helping these cats and their kittens. The best way to help stray and feral cats is by ensuring they are spayed and neutered. Cats are very prolific and some kittens can become sexually active as early as 4 months old. Your best bet would be to get in touch with animal services, a shelter, or a humane society in your area, they can help you with low-cost spay and neutering and some associations will even help you find the kittens a forever home.

Hi Marsha, feral cats are different than strays, and some associations compare them to wild animals. You can learn some of the differences here: https://www.catster.com/ask-the-vet/feral-cat-vs-stray-cat/
We have heard stories of some ferals warming up to allow some human closeness, but some of them never do. Thanks for reading us, best wishes.

Hi Tracey, you are right, animal shelters, humane societies, and animal services usually have TNR programs to help reduce the overpopulation of stray and feral cats. Thanks for your comment.
