Name a nonverbal cue used to assess pain in small animals.

• A. Licking or guarding the body
• B. Increased appetite
• C. Vocalization during rest
• D. Reduced activity

Answer: (D)

Nonverbal cues are how we gauge pain in animals that can’t tell us how they feel. Reduced activity is a robust, general sign across small animals: they move less, rest more, hesitate to walk or explore, and may settle into a comfortable position to avoid further discomfort. This change in overall activity reflects the effort and guarding that pain causes, making it a reliable indicator of pain severity in a variety of situations.

Licking or guarding a specific area can indicate localized pain but isn’t as universally tells-tale of overall discomfort. Increased appetite often decreases with pain rather than increases, so it’s not a dependable cue for pain. Vocalization can occur with pain, but not all animals vocalize, and some may be quiet due to fear or sedation, so it’s less consistently reliable than a change in overall activity.
