How to treat fever in cats

When a cat suddenly becomes lethargic and feels warm to the touch, it often indicates that they have a fever. Fever in cats can be a sign of a serious health issue that requires immediate attention. In this CURE FIP™ article, we will thoroughly discuss how to recognize the signs of fever in cats, its causes, and the home remedies that can be used, including safe fever medications for cats and effective natural treatments. We will also cover fever as a symptom of Feline Infectious Peritonitis (FIP), a serious and often fatal disease in cats.


What is Fever in Cats and Why Does It Happen?


Fever in cats is a condition where the cat's body temperature rises above the normal range as a response to infection or inflammation. The normal body temperature for cats ranges from 38.1°C to 39.2°C. When a cat’s body temperature exceeds this range, it can be confirmed that the cat is experiencing a fever.


Why do cats get fevers? Fever is the body’s natural mechanism to fight off infectious agents such as bacteria, viruses, or fungi. Other conditions, such as reactions to vaccinations, inflammation from injuries, or even severe stress, can also trigger fever in cats.


Keep An Eye for Fever Symptoms in Cats 


Recognizing the symptoms of fever in cats is crucial for providing appropriate care. Here are some signs that may indicate your cat has a fever:

  • Lethargy and Inactivity: Cats with a fever tend to be less active and sleep more than usual.

  • Loss of Appetite: Cats with a fever often lose interest in food and water.

  • Warm Body: Parts of the cat’s body, such as the ears, paws, and belly, may feel warmer.

  • Shivering: Some cats may shiver even if the surrounding temperature is not cold.

  • Seeking Hidden Spots: A sick cat often tries to find quiet and hidden places to rest.


How to Measure a Cat’s Body Temperature

Measuring your cat’s body temperature is an important step to confirm if your cat has a fever. Here’s the correct way to measure a cat’s body temperature:


  • Use a Digital Thermometer: Ideally, use a digital rectal thermometer designed for animals.

  • Lubricate the Thermometer: Apply a lubricant like petroleum jelly to the thermometer.

  • Calm Your Cat: Wrap your cat in a towel to prevent sudden movements and reduce stress.

  • Insert the Thermometer Carefully: Insert the thermometer into the cat’s rectum about 1-2 cm, and hold it until the thermometer beeps.

  • Read the Temperature: If your cat’s body temperature exceeds 39.2°C, it indicates that your cat has a fever.


How to Treat a Cat’s Fever Naturally 


For cat owners who prefer a natural approach, here are some ways you can try to reduce your cat’s fever at home:


  • Cold Compress: Use a cold, damp cloth and place it on the cat’s warm areas, such as the ears and paws.

  • Provide Coconut Water: Coconut water can help hydrate a feverish cat due to its high electrolyte content.

  • Plain Chicken Broth: Giving plain chicken broth can help increase fluid intake and provide additional nutrition.

  • Place in a Cool Area: Ensure the cat rests in a cool and comfortable place to help lower its body temperature.


Safe Fever Medications for Cats


If natural treatments are not effective and the fever persists, you may need to consider fever medication for cats available at pharmacies. However, it is very important to consult with a veterinarian before giving any medication. Here are some options that may be recommended:


  • Antibiotics: If the fever is caused by a bacterial infection, a veterinarian may prescribe certain antibiotics.

  • Anti-Inflammatory Medications: These can help reduce fever and inflammation, but should be used under veterinary supervision.

  • Intravenous Fluids: In cases of severe dehydration, a veterinarian may administer IV fluids to stabilize the cat’s condition.


Fever as a Symptom of FIP in Cats


Feline Infectious Peritonitis (FIP) is a serious and often fatal disease caused by a mutation of the feline coronavirus. Fever is one of the most prominent symptoms of FIP and is often persistent and difficult to treat with regular care.


Signs of Fever Related to FIP

  • Persistent High Fever: Unlike other fevers, the fever associated with FIP is continuous and hard to treat.

  • Fluctuating Temperature: FIP can cause the cat’s body temperature to fluctuate.

  • Additional Symptoms: FIP can also cause weight loss, abdominal swelling, lethargy, and a decrease in appetite and drinking, along with fever.


Diagnosing and Managing Fever Related to FIP


Diagnosing FIP involves a combination of clinical signs, blood tests, and veterinary examination. If you suspect your cat is experiencing fever related to FIP, the first step is to visit a nearby veterinarian or clinic for an immediate check-up.


When to Take Your Cat to the Veterinarian


If your cat’s fever lasts more than 24 hours or is accompanied by severe symptoms such as vomiting, diarrhea, or difficulty breathing, it is best to take your cat to the veterinarian immediately. Prolonged fever can lead to serious complications such as dehydration or organ damage, requiring urgent medical care.

  • Monitor Temperature Regularly: Check your cat’s body temperature regularly to ensure their condition does not worsen.


Preventing Fever in Cats


Preventive measures can help reduce the risk of fever in cats. Here are some prevention tips:


  • Regular Check-Ups: Routine visits to the veterinarian help detect health issues early and ensure your cat receives necessary vaccinations.

  • Flea and Parasite Control: Parasites can carry infections, so make sure to keep your cat free from fleas and worms with regular treatments.

  • Safe Environment: Keep your cat indoors or supervise them when outdoors to minimize exposure to infectious agents or harmful substances.
