The drawing style is cute! I love the anime-style eyes!
I do feel the anatomy could use a bit work. The hocks are too high, and the chest shouldn't be sticking out. Also, given the position of the cat's head, both ears should be facing forwards.

I suggest practicing to draw cats by using photos for references- it helps a ton, and over time you'll begin to see improvement in your work through lots of practice.
Keep it up! c:
