If we are comfortable listening to the creatures as described above, learning their unique languages follows naturally. Each species has its own set of signs. Also, I find each species has his or her own place from which to communicate. For instance, dogs and cats seem to center their contact in the heart. They are very intelligent, but they deeply need to know what their person is feeling .
Birds are very sound-oriented, and want to converse at length about important issues.
Pot-bellied pigs, oddly enough, are very like the birds. I find Mollie always fully involved in her head, she wants me to engage her intellect and challenge her wit. Each individual within a species also has his or her own set of signs and ways of expressing. A colleague of mine has several cats, and although to an outsider all their meows may sound the same, he is aware that each meow from each cat is completely different, requiring a completely different response. One is telling him to fill the water bowl, another is saying it's time to play, another is saying it's treat time.
