My cat is a undercover detective

I've been having this cat for the last four months and i just notice that he is growing boy parts, i just can't believe that it is not a girl ,it's a boy ! I am so sad because i don't like boy cats actually i have two more girl cats Luna and Paloma the thing is that I am in love with him the hard part is that I need a new name for him and I have to accept that I have a male cat in the house. This is the reason why im giving up his name..kinda funny..
