Always happy to look at boop. stuff. That triangle with one knocked in is definitely a great shape to hit, and can be easy to do it (just push that connecting diagonal piece in).
While maybe not end game, there is also value in learning how to play when up 3 cats or down 3 cats at the start (Though applies other places). Namely, if you are up 3 cats you should win. Put one cat down in the middle and then just putz around with your kittens, you can eventually either get more cats or your opponent will place a kitten next to your cat. If they do, just double up cats on the far side since the kitten stops pushing, and they now have to spend every turn putting a kitten down to block your cats.
From there, the easiest way to win is to just set it up (by pushing kittens out of the way with your kitten) so that by blocking your cats, they create three in a row and have to pick up their kittens, opening the win back up.
