Detailed explanation-2: -Most animals use vocalised sounds to communicate with one another and with other species. For example, a cat hisses when it feels threatened or purrs when it feels comfortable. These sounds are the cat’s way of communicating whether it wants to be petted or not… proceed at your own risk.

Detailed explanation-3: -Pheromones are chemical signals that have evolved for communication between members of the same species. A pheromone signal elicits a specific reaction in the receiver, for example, a stereotyped behavior (releaser effect) or a developmental process (primer effect).

Detailed explanation-4: -Animals communicate using signals, which can include visual; auditory, or sound-based; chemical, involving pheromones; or tactile, touch-based, cues.
