Which vocalization indicates warning signs such as aggression?

• A. Purring
• B. Growling/hissing/snarling
• C. Chirp
• D. Moan

Answer: (B)

Vocal signals show how an animal feels, and a growl, hiss, or snarl is a classic warning vocalization that the animal is uncomfortable or feels threatened and may escalate if approached. It’s the behavior most closely associated with aggression or defensive aggression, serving to deter others and buy time to create distance. Purring typically signals contentment or relaxation, not aggression. A chirp is usually a vocalization for greeting or excitement, and a moan can indicate discomfort or distress rather than a warning to back off.
