No, there is no Neopets Kass Basher cheat that we know of. However, I would only hit the Kass when the wind is at 9 m.p.h. (occasionally, if you're lucky, you can catch it at 10 m.p.h, but this is very rare.). I would also hit the kass when it's beak is almost at the bluemaroo's neck. Once you hit the kass, hold down the left mouse button until the kass is beginning it's descent from the air. Once it descends, let go. Then, click a lot of times when the kass hits the ground for it to bounce and go farther. Eventually, you'll get the bat and it'll be much easier.
I haven't gotten the bat either. I'm still working with the stick! Good luck!

There is also another rare happening. Sometimes, you could get to use the tree instead of the bat, and that hits the Kass VERY far, but it's VERY rare.
Theres also another secret where if you hit the Kass and on the ground, theres a small grey stone, click it, press restart game (Where you're at the main menu again) and when you go back to playing and hit the Kass, instead of a Turtum telling your score, there will be a Drackonack (SP?)
