Two cats have wandered to our house

One has been with us for several weeks. Can not get close enough to know if male or female, but I am guessing female from a hint of calico coloring. Mainly dark gray and white. She has been living in our shed and we feed her there.

The second one is a new arrival and is a gray and black tabby. I had to rescue it from a tree about 20 feet up this evening. It could be a male but I did not check before I let it go. He was used to being handled by humans and did not run from us. I would expect that he will be around the house tomorrow.
