I am really not sure how many pet that I have had, but it was quite a few over the years.
Actually, I have mostly lived out in the country; so there were usually the farm critters as well. I have enjoyed these usually as much as the more conventional pets, and my very favorite was the llama.
I am not quite sure whether he fits into the category of livestock or a pet; but for me, he was just a pet, since I didn't do anything with him besides just enjoy having a llama.
He would come right into the house with me; and lie down on the rug. When he talked, he made a kind of whining/humming noise; so that was how I "talked" back to him. In the morning, I would go out to the pasture and call him, and he would always come running right up to me, and greet me with a soft llama-kiss.
