My name is Jack!

I have been caring for an outside cat that someone left behind since this past April. At that time I did not know the gender. I found she had two kittens in a barn near where I live and were 6 wks old at that time. I started feeding all of them over at the barn, and then eventually moved to an outdoor shelter in my yard, and they are currently living inside of my enclosed front porch. Unfortunately, it is not heated, but have been using a space heater that has been a great help. Jack is a very sweet, playful kitten, and has gone from being pretty shy and scared to very friendly and playful. I am unable to afford to keep them as much as I would love to!! Looking for homes for Jack and his brother Seth. Ultimately, I would love to keep them together, but I realize that might not be possible. They are currently 5 mo old
