Huh?

We don't have to talk to a dog to know it has differing experiences from us, though granted I would say dogs are probably one of the closer animals to humans as far as that goes. That's beside the point though, because we can easily derive that the eyesight and scent dogs have create a different sensory experience than we have.

Science has allowed us to begin to understand the experience of other animals, we don't have to "talk to them".

Bats clearly experience reality differently than we do, Bugs as well, etc... It's all essentially the function of an output determined by chemical/sensory inputs. That's basically what op was getting at.
