Kittens looking for homes

I have two 3.5 month old kittens who are looking for homes. Gray is a boy, tabby gray/orange is a girl. I found them outside at 6 weeks old and took them in. They are very affectionate and playful, love being held and purr like crazy. They get along with other cats and big dogs, and would do fine with kids. I just had both spayed/neutered, vaccinated, and microchipped, both are FIV and FeLV negative. $10 rehoming fee just to make sure they go to good homes. I'm located in Fort Worth. If I can't find them homes they will go to the shelter.
