I like the idea and I think this could be a lot of fun with some added polish. I would get stuck on walls when jumping into them. Not sure if this was intentional or not - cats are extremely good climbers after all. If it was, then I think a wall jump would be more satisfying. The background is cool. If you gave it a parallax effect it would look even better. Meow mechanic was funny; maybe make it so that meowing gets the dog's attention - kind of like the pebble.
