A human baby will engage in taking turns in a conversation.
When DCat meows & I meow back & he meows again... is he conversing or is he just responding to each meow as a bit of brand new stimulus (no continuity).
A human baby will converse back if I make talk to it, just b/c they like conversation. A human might try to carry on the conversation stopped 10 minutes ago.
A cat only seems to converse back if it wants to be fed!
