As a cat owner, recognizing when your feline friend is under the weather is crucial. One common health issue cats face is fever. But how can you tell if your cat has a fever? This article will guide you through the signs to watch for and what steps to take if you suspect your cat is running a temperature.
Understanding Cat Fevers

Before we dive into the signs, it’s important to understand what constitutes a fever in cats.
What is a Normal Temperature for Cats?
A cat’s normal body temperature ranges from 100.4°F to 102.5°F (38°C to 39.2°C). Any temperature above 103°F (39.4°C) is considered a fever in cats.
What Causes Fevers in Cats?
Fevers in cats can be caused by various factors, including:
- Infections (bacterial, viral, or fungal)
- Inflammatory conditions
- Certain medications
- Heat stroke
- Immune system disorders
7 Signs Your Cat May Have a Fever

While you can’t always tell if your cat has a fever just by looking, there are several signs that might indicate your feline friend is running a temperature:
1. Warm Ears, Nose, or Paws
Gently touch your cat’s ears, nose, and paw pads. If they feel warmer than usual, it could be a sign of fever.
2. Lethargy or Decreased Activity
If your usually active cat becomes sluggish or prefers to sleep more than usual, it might be due to a fever. Why is my cat shaking might be another question you’re asking if you notice unusual behavior.
3. Loss of Appetite
Cats with fevers often lose interest in food. If your cat is skipping meals, it’s a cause for concern.
4. Changes in Behavior
A feverish cat may become more irritable or seek more attention than usual. Some cats might hide when they’re not feeling well.
5. Rapid Breathing or Heart Rate
If you notice your cat breathing faster than normal or feel a rapid heartbeat, these could be signs of fever.
6. Dehydration Symptoms
Check for signs of dehydration such as sunken eyes, dry mouth, or skin that doesn’t snap back quickly when gently pinched.
7. Shivering or Hiding
Cats with fevers may shiver or seek out warm spots to hide. If you find your cat in unusual, warm places, it could be trying to regulate its body temperature.
How to Check Your Cat’s Temperature?

The most accurate way to determine if your cat has a fever is by taking its temperature.
Using a Digital Thermometer
- Use a digital thermometer specifically designed for pets.
- Lubricate the tip with petroleum jelly.
- Gently insert the thermometer about 1 inch into your cat’s rectum.
- Wait until the thermometer beeps (usually about 60 seconds).
- Remove and read the temperature.
When to Seek Veterinary Help
If your cat’s temperature is above 103°F (39.4°C), or if you notice multiple signs of illness, it’s time to contact your veterinarian.
What to Do If Your Cat Has a Fever?

While waiting to see the vet, there are some steps you can take to help your cat feel more comfortable:
Home Care Tips

- Provide fresh, cool water to prevent dehydration.
- Create a quiet, comfortable resting area.
- Monitor your cat’s behavior and symptoms.
When to Contact Your Vet Immediately
Seek immediate veterinary care if:
- Your cat’s temperature exceeds 104°F (40°C).
- The fever lasts more than 24 hours.
- Your cat shows signs of severe lethargy or difficulty breathing.
Prevention and Long-term Care

While you can’t prevent all illnesses, there are steps you can take to keep your cat healthy:
Regular Check-ups
Schedule regular veterinary check-ups to catch potential health issues early. Your vet can also advise on how to treat my cat’s eye infection at home if that’s ever a concern.
Maintaining a Healthy Environment
Keep your cat’s living area clean and stress-free. Ensure they have a balanced diet and plenty of fresh water.
Vet Advice
Knowing how to tell if your cat has a fever is an essential skill for every cat owner. By recognizing the signs early and taking appropriate action, you can help your feline friend recover quickly. Remember, when in doubt, always consult with your veterinarian. They can provide the best guidance for your cat’s specific health needs.
If you notice other unusual behaviors like why is my cat peeing on my bed, it’s always best to consult with your vet, as these could be signs of other health issues or stress.
Stay observant, trust your instincts, and don’t hesitate to seek professional help when needed. Your cat’s health and well-being depend on your attentiveness and care.
