I do. I talk with them like they know my language, I do cutesy talk and also try to talk to them in their native language (ie. Barks, meows, and body language). when I'm walking I sometimes whistle at the birds (I've actually got a call down) and the squirrels, I chirp/chitter at them XD the only one I know is the stuff I got when camping. I noticed if I would sleep outside quite often a squirrel would start chirping/chittering at me, I think it's a warning really because when I do it other squirrels they will run away very fast. Who knows, just some thoughts from a country/city boy.
