If a squirrel aspirates fluid into its respiratory tract, during the next 24-48 hours you should be especially alert for signs of pneumonia.

• A. 48-72 hours
• B. 24-48 hours
• C. One week
• D. Never

Answer: (B)

When material is aspirated into the lungs, the risk of pneumonia is highest as the inflammatory and infectious process begins to develop in the next day or two. For a squirrel, signs of pneumonia commonly become noticeable within about 24–48 hours after the aspiration event. That makes this window the critical period to watch closely, because recognizing problems early allows timely supportive care and treatment, which can improve recovery. Be alert for changes such as faster or more labored breathing, lethargy, reduced appetite, nasal discharge, or other signs of respiratory illness. While monitoring remains important beyond this window, the 24–48 hour period is when pneumonia is most likely to first appear following aspiration.
