It inspired me to make this, so thanks.

I don't find your comic all that funny. It just sets up a situation, which would be okay except that it's not, in itself, a funny situation. It's a situation that has the potential to be funny, but you don't do anything with it. Try inserting something unexpected into it. Have the guy say "So, who wants to play checkers?" Or make the guy (or the girls) gay. Or switch out one of the girls for a duck, then have the guy react to that somehow. Maybe the catgirl is supposed to elicit this effect in your strip, but if so, it doesn't really come across.
Good luck, and welcome to Stripcreator.
