Wait for Merengue to ping you so you can move her into your other town. You might as well take advantage of the fact that you have her. Good luck with your all cat town I just have this one comment:
Why don't you want Kid Cat? He's better than Stinky. I know everyone has their own opinion, but I'm going to do everything in my power to shame you into getting Kid Cat. Kid Cat is a superhero. Stinky is a super zero. People will make fun of you for having underwear head in your town. Having an all cat town without Kid Cat is sacrilegious and the cat gods will be angry at you. If you really want Stinky though, I'll just go and cry in a corner ;-; (not really, it isn't my town after all)
