Great little game with nice sprite-animations and I also like the controls. The cat is easy to control, once you get used to it, also when she's at higher speed. I recognized, that the highscore doesn't seem to save to the disk, if you get over 2500 points, but that might be a problem with the emulators, as I haven't played the game on a real C64 yet. I'll do that, though. Good work so far.
