How to Know if Cat Has Fever

How to Know if Your Cat Has a Fever

Cats are known for their independent nature, but they rely on their owners to take care of them when they are unwell. Like humans, cats can get a fever, which is a common symptom of an underlying illness. As a responsible pet owner, it is important to be able to identify the signs of a fever in your cat. Here are some key indicators to look out for:

1. Increased body temperature: A normal temperature for a cat ranges between 100.5°F and 102.5°F. Use a digital thermometer to take your cat’s temperature rectally. If it exceeds 102.5°F, it may indicate a fever.

2. Lethargy and lack of appetite: Cats with a fever often become lazy and uninterested in their surroundings. They may also lose their appetite and show a lack of interest in food and water.

3. Shivering or trembling: Just like humans, cats may shiver or tremble when they have a fever. This is their body’s way of raising their temperature.

4. Warm ears and dry nose: Sick cats often have hot ears and a dry nose. However, it is important to note that these symptoms can also be indicative of other health issues, so it’s crucial to consult a veterinarian for a proper diagnosis.

5. Increased heart and respiratory rate: A cat’s heart and respiratory rates may increase when they have a fever. You can observe this by paying attention to their breathing and feeling their heartbeat.

6. Dehydration: Fever can cause increased fluid loss through panting and sweating. If your cat is not drinking enough water or has dry gums, it may be a sign of dehydration.
