How Do I Know if My Cat Has a Fever?

As a loving cat owner, you want to ensure your feline friend is always healthy and happy. But cats are masters at hiding their discomfort, making it tough to tell when they’re not feeling well. One common ailment that can be tricky to spot is a fever.

A fever in cats is a sign their body is working hard to fight off an infection or illness. While it’s a natural defense mechanism, a high fever can be dangerous. This article will guide you through the signs of fever in cats, explain the causes, and advise you on what steps to take.

Recognizing the Signs

First, let’s look at the common symptoms of a fever in cats:

Loss of Appetite: One of the first things you might notice is your cat turning their nose up at their favorite food. This could be due to a reduced sense of smell and taste, a common side effect of a fever.
Lethargy: A feverish cat may seem unusually tired and sleep more than usual. They might not show interest in playing or interacting with you like they normally do.
Hiding: Cats instinctively hide when they don’t feel well. If your usually social cat suddenly prefers to be alone in a secluded spot, it could be a sign of illness, including a fever.
Changes in Grooming Habits: Cats are generally meticulous groomers. If your cat’s coat starts looking matted or unkempt, or if they stop grooming altogether, it could be a sign they’re not feeling their best.
Warm Ears and Paws: While not a foolproof indicator, a cat with a fever might have noticeably warm ears and paws.
Increased Respiratory Rate: You may notice your cat breathing faster than usual, even when resting. This is because a fever can increase their metabolic rate, requiring more oxygen.
Dehydration: Fever can lead to dehydration. Check your cat’s gums – if they seem dry, sticky, or pale, your cat may be dehydrated.

Remember that these signs can also be symptoms of other health problems, so it’s crucial to confirm if your cat actually has a fever.

Checking Your Cat’s Temperature

The most accurate way to know if your cat has a fever is to take their temperature. Here’s how:

Use a digital rectal thermometer specifically designed for pets.
Lubricate the tip with petroleum jelly.
Gently lift your cat’s tail and insert the thermometer about 1 inch into the rectum.
Wait for the thermometer to beep, indicating a reading.
Clean the thermometer thoroughly after use.

A normal temperature for cats is between 100.4 and 102.5 degrees Fahrenheit. If your cat’s temperature is above 102.5, they likely have a fever. A temperature higher than 106 degrees Fahrenheit is a medical emergency, and you should take your cat to the vet immediately.

What Causes a Fever in Cats?

A fever is a symptom, not a disease itself. Here are some common causes of fever in cats:

Infections: Bacterial, viral, and fungal infections are common culprits of fever in cats.
Inflammation: Conditions like arthritis or pancreatitis can trigger a fever.
Trauma or Injury: A fever can occur after an injury, such as a bite wound or a fracture.
Toxins: Ingesting poisonous substances can also cause a fever.
Immune-mediated Diseases: These are diseases where the immune system attacks the body’s own tissues, potentially leading to a fever.
Cancer: Some types of cancer can cause fever.

What To Do If You Suspect Your Cat Has a Fever

If your cat shows any signs of a fever or has an elevated temperature, it’s vital to seek veterinary attention.

Do not try to treat your cat’s fever at home with human medications, as many are toxic to cats and could worsen their condition.
Instead, take your cat to the vet for a proper diagnosis and treatment plan.

The vet will likely perform tests to determine the underlying cause of the fever, such as blood work, urinalysis, or imaging studies.

Caring for a Cat with a Fever

While your cat recovers, here are some ways to help them feel more comfortable:

Encourage Hydration: Make sure your cat has access to fresh, clean water at all times.
Provide a Comfortable Resting Area: Create a quiet, cozy space for your cat to rest and recover.
Follow Your Vet’s Instructions: Administer any prescribed medications as directed by your veterinarian.

Final Thoughts

Recognizing the signs of fever in your cat can help you act quickly and get them the treatment they need. Remember, a fever is a sign that something is wrong, so it’s always best to consult your vet for professional advice and care.
