Newest Family Member?

A few days ago, I found a stray cat on our front porch. I thought it was the neighbor's across the street, so I caught it and brought it over. It, however was not their cat. I checked with other neighbors, and they had seen the cat around, but did not know if it had an owner. So I took a picture and put up signs, and brought the kitten inside. It's been a few days, and no one's called about the cat.

When I first brought the cat in, my husband's first words were "maybe we should keep it." And my youngest promptly started calling the kitten Joshua. So meet our newest family member:

Now my sister wants to give us another stray kitten she found in her backyard.
