Ah, I remember this one vividly. The endless survival math that pits cats versus dogs via math battle.
This one's a bit of a heartbreaker because having the right cats makes it impossible to lose the game, and I have a picture to prove that.
You may notice the combination of cats which I have on the bus, and realize how comically strong this is in comparison to the dogs.
Endless games are a "Losing is Fun" kind of paradigm. This batch of cats will either NEVER be beaten by the linear +20 per round, or take so long that you simply quit before you come close to it.
That said, I gave this a 4/5 for fun because I went quite a few rounds before just giving up, which is an indicator that yes, watching numbers team up and beat down other numbers is still fun for a while.
