This is Leo, or "cat-dog" as most people call him. The reason for that is because he's BIG, and he was always the bigger kitten of the litter. He also has taken up a habit to sleep on my bed (as shown here) because he either likes it, or likes that the AC reaches him from there.

Because of his size, he's very lazy and often "fights" his little sister while lazing about. He's sadly NOT a cat to be played with because of his brute strength and knack of biting when upset. Me being the one who spends the most time with him have gotten several nasty cuts/scratches in the past.
