Short but great! And I fully support the message against those dogs breeding farms!
As for the detailed content, the part with the dog could use the "Who let the dogs out?" track and the cat stage - which I liked the most - reminded me of an old cartoon in which a black cat was helping a white cat by causing bad luck to a dog chasing it. Hey, you could make a game about a cat with such super powers!
Just one more thing: I don't believe I've ever seen such a HUGE Newgrounds medal ;-)
Good luck, I hope your game will be appreciated and awarded.
