Good Cat - Free For A Very Good Owner

I have a black male cat (around 6 months old) living in my garden. I'm willing to give it him a very good owner.

He's not totally black, have 2 white spots, below the neck and on the belly.

The cat is healthy and doing good because I take care of him. I can afford this, but I cannot take him home, as I already have 2, and it's enough for me. Besides, one of my cats is almost identical to this third by her look and behaviour.

By the way, behaviour is really nice. They murr, they like to be pet, and very nice and tender creatures, that are supposed to be very good with kids (no fighting or scratching).
