I call all my critters "babies" or "chick chick". For some odd reason my cat Sparky won't respond to "kitty kitty", but when I call "chick chick" he comes running. My dogs I also call stupid, nasty dogs, stinky poos. Of course nasty dogs is after they roll around in the mud by the lake, and stinky poos are after arguing with a skunk.
My guineas think they are chickens, and my chickens think they are supposed to sit on my feet or ride on my scooter with me.
I wonder how my babies would react if I called "companion animals". Probably give me the stink eye.
