It's crucial to consult a veterinarian immediately.
Here are some reasons why a cat might have a cold nose and ears:
* Dehydration: This is a common reason for a cold nose. If your cat isn't drinking enough water, their nose might become cool and dry.
* Cold weather: Cats can get cold, just like humans. If your cat is spending time in a cold environment, their nose and ears might get cold.
* Illness: A cold nose and ears can be a sign of illness.
* Medications: Certain medications can cause a cold nose and ears as a side effect.
Only a veterinarian can diagnose the cause of a cold nose and ears in your cat and recommend the appropriate treatment. Please don't hesitate to contact your vet or an emergency animal hospital right away.
