Your best mate/companion

Who here has a best mate/companion that is not a dog?
Even when my old dog was still alive my little mate use to keep me company while I was reloading or cleaning rifles. My dog Dozer would be asleep at my feet and Cookie would be playing around on the reloading bench. Cookie is a Black Headed Caique and mad as a cut snake.
She will spend all day sitting on my shoulders or climbing around.
