No, the big cat in the last pic is not related... he's just another cat in the yard... The little guy has no relatives here as I brought him from the parking lot at work where I found him screaming last week.

Good news- He's now playing with another tiny kitten (well, he's much bigger but he was the same size when he came here ) and they are having a great time... he found a friend! I tried to film it, but it's too dark already. maybe tommorow!
