Cats and Dogs

Last week my mom brought a little dog to our house a little dog. He is cute, but I don't like the dogs - they are annoying and noisy. I prefer cats. They are good company. When I was little I wanted to have all animals, but my mom just bought a cat. He was my best friend. This is the reason that I prefer to cats.

[I prefer cats myself, but I don't mind dogs.  You can say "I prefer cats to dogs" or "I prefer cats over dogs.", but "I prefer cats" is understood from the context.]
