Found cat with 2 kittens

Hello, There is a young female black cat with some white markings on face and paws hanging out around my house with her two kittens. We think the kittens are about 1 month old, maybe younger. It appears that her stomach is shaved, indicating that perhaps she was recently spayed or had surgery. She is friendly and will let us pet her, and the kittens are very playful, but afraid of people. If this is your cat, please email me at 320Brooks@gmail.com. Or, if you have information about this cat (maybe you've been feeding her?), please let us know. We want to help these cats out!
