Others already said it, but the art is so good! Well done :D
The mouse was jittering a bit for me, though this might be an issue on my PC as I've had trouble with other browser games on itch. I guessing you are using Godot(?), so maybe you'd want to set the 'mode mode' to 'confined'. I think that would help with not accidentally clicking outside the game area.
The audio of the cat could have more variations - it becomes a little repetitive after a few times.
Overall, great work!
