I liked the cute sprite. The random food bowls fit the theme well, jumping all over the room looking for food is a very authentic cat experience. And I always appreciate more platformers.
Running and jumping felt good, but the collision detection is very jittery and should be more stable. It's either a frame to late or overshoots. And there should be walls on the side to not fall off. But for 3 days with your second Unity project its fine.
