Thanks for the advice. I put a large box in the garage with a towel in it and food and water. The mom cat was very nice about letting me move her kittens. She just watched me and followed me. I fed her and she ate 2 whole bowls of food. I also left the windows open in the garage for air circulation.
The neighbor saw what I was doing and came over. She said when theyre older she wanted one.

Then, my best friend came over for our cookout and said she wanted one too.

So all I would need to do is find a home for one kitten and its mommy.
