Yes, I talk to my pets all the time. Of course I don't expect them to answer back, but I have noticed that they are responsive to my voice so I like to speak to them because I think it's part of their routine. We "talk" during their meal times and when we have play time. The cats are very affectionate and really seek out human interaction so there are many other small conversations we have throughout the day. I have noticed that if things get quiet for awhile they will sometimes walk into the room I am in and look up and meow once, as if they want to start a conversation.
