Which finding may indicate an Upper Respiratory Infection in cats?

• A. A normal variation in cats
• B. Irregularly prominent nictating membrane
• C. Dehydration signs
• D. Dental disease signs

Answer: (B)

An irregularly prominent nictitating membrane points to ocular irritation or conjunctival involvement that often accompanies a feline upper respiratory infection. When the nasal and ocular surfaces are irritated by viral or bacterial URIs, the third eyelid can appear more visible as the eye responds to irritation and discharge. This makes it a more disease-relevant sign than simply a normal variation or non-URI findings. A normal variation isn’t a sign of illness, dehydration signs are nonspecific and can occur with many conditions, and dental disease signs reflect oral health issues rather than a respiratory infection. The presence of a more visible third eyelid aligns with the ocular manifestations that frequently accompany feline URIs.
