This is a cruel game :( The kitty is adorable! Jokes aside, this game is fairly well made! Found all 9 solutions eventually, and it's quite fun trying to figure out each of them. I also like the graphics especially the kitty, and the art style and the gameplay fit quite nicely together too. Nice job.
For some comments, I'd say the platforming is a bit difficult, and it's quite easy to overshoot/undershoot the jumps. This is especially noticeable when climbing the small platforms on the cat tree. I will also point out that the hidden path that leads to the top of the toilet is a bit too hidden, and it feels like I've found it via blind luck. But other than that, the game is nicely done, and you should be proud of yourself for making it!
