How Can You Tell if a Cat Has a Fever?

Cats are known for their ability to hide illness and discomfort, making it difficult for pet owners to determine if their feline friend is unwell. One common indicator of illness in cats is fever. Just like humans, cats can develop a fever as a response to an infection or underlying health issue. However, detecting a fever in cats can be challenging, as they tend to mask their symptoms. Here are some signs to look out for that may indicate your cat has a fever:

1. Elevated body temperature: The normal body temperature for a cat is around 100.5 to 102.5 degrees Fahrenheit. Anything above this range may indicate a fever.

2. Lethargy: If your usually active cat becomes unusually lethargic and lacks interest in playing or interacting, it could be a sign of a fever.

3. Loss of appetite: A fever can cause a cat to lose its appetite. If your cat suddenly stops eating or shows a significant decrease in food intake, it may be due to an underlying fever.

4. Shivering or trembling: Cats may experience chills and shivering when they have a fever.

5. Dehydration: Fever can lead to increased water loss through sweating and panting. Check for signs of dehydration, such as dry gums and sunken eyes.

6. Warm or hot ears: Gently feel your cat’s ears. If they feel unusually warm or hot to the touch, it could be an indication of a fever.

7. Behavioral changes: Cats with a fever may display changes in behavior, such as increased aggression, hiding, or seeking excessive attention.

Depending on the cause, treatment options may include antibiotics, antiviral medications, or supportive care to reduce the fever and manage the symptoms.
