Beerus is a cat-like creature who is also called the God of Destruction. He is known for his extreme power and strength and is capable of destroying planets.
Despite his power, he has adopted behaviors similar to a cat. Beerus can lazy, clean himself like a cat would, and is very passionate about eating. He also has the tendency to think of himself as superior to everyone else, even bossing around the likes of Vegeta.
Still, Beerus has shown respect to others, especially Master Roshi and Goku. He is even respectful in the way that he speaks to and of others, granted that he is capable of destroying everything immediately.
