Nice male cat for a new home (Jacksonville)

This nice big male kitty came to us when he got injured.
Don't know how.
He stayed in the back shed and was completely wild.
We opened our hearts and fed him, and gradually he opened his heart to us as well.
He is really kind and gentle, but prefers to be the only cat you pay attention to.
This is why we need to rehome him.
Sad.
His perfect new home would be where he is the only pet around.
He tolerates our other two male cats, but attacks on sight our only small female cat.
We tried, but can't have this keep happening.
We take him into the mancave at night and sleep with his and he is a pure love.
I will charge a $20 rehoming fee only because i do not want him to wind up in some medical research lab.
Please give him the abundant love I know he will give you.
