Free cat to good home

Very sweet male cat about 1.
5 ! Needs to be in a home with no other cats.
Recently adopted but he does not get along with my current cat.
I hate to have him go.
I think he was also previously indoor / outdoor as he does try to go outside.
He is neutered and microchipped and vaccinated.
Would like to make sure he goes to a good home.
He’s very sweet and loving just not with my cat.
Would like to rehome him quickly.
