A stray cat has adopted our family and she had a litter somewhere in a nearby field. She started to hang out at our house full time when she stopped nursing. Then I started to notice her belly getting bigger and bigger. She went back to her old nesting area somewhere in the field and she had her kittens just the other day. I knew when she had her kittens because she came back to our house skinny and still dirty from the birth. She showed up today with a kitten in her mouth. The kitten appears to be fine and healthy and we set up a safer place for them both, but do I need to do anything for them besides feed mom? I have never owned a cat before so this is all new to me.
