Do you have a COG (cat that thinks he/she is a dog)?

I have a wonderful Russian Blue cat named Gus (short for Gus toff). He fetches with his favorite toy a white hair scrunchie. I will throw it down the hall, he runs, picks it up and drops it at my feet. He also walks around and chews on things i.e. the chair, desk, dresser. He is Sooo funny. He also meows real loud and answers when you call him, just like a dog. Anyone have a cat like that as well? What does he/she do? Tell in detail. Need to laugh today.....
