Just like humans, cats can get a fever when their bodies are fighting an infection or illness. As a responsible pet parent, it's important to identify the symptoms early and get the right treatment promptly. A fever is not a disease but a symptom that something else may be wrong.
This blog will help you understand what fever in cats means, what causes it, how to spot it, and what to do next.
What is a Fever in Cats?
A fever is an increase in your cat’s normal body temperature. A healthy cat’s body temperature ranges between 100.5°F to 102.5°F (38°C to 39.2°C). A cat is typically considered to have a fever when its body temperature rises above 103°F (39.4°C).
When the temperature exceeds 106°F (41.1°C), it becomes dangerous and could cause damage to organs or be life-threatening.
Causes of Fever in Cats
There are several reasons why a cat may develop a fever:
- Bacterial infections (wounds, abscesses, respiratory issues)
- Viral infections (feline leukemia, FIV, or feline infectious peritonitis)
- Parasites such as ticks or fleas
- Inflammatory conditions like pancreatitis or arthritis
- Toxins or poisoning
- Cancer
- Unknown causes (called fever of unknown origin)
Signs and Symptoms of Fever in Cats
Fever is not always easy to detect, especially since cats tend to hide their discomfort. Look out for the following symptoms:
- Lethargy or tiredness
- Loss of appetite
- Shivering or rapid breathing
- Warm ears, paws, or nose
- Reduced grooming
- Hiding or avoiding people
- Dehydration
If your cat seems “off” and exhibits any of these signs, it’s best to take their temperature using a rectal thermometer or consult a vet for an accurate diagnosis.
How is Fever Diagnosed?
A veterinarian will examine your cat and may perform tests like:
- Physical check-up
- Blood tests
- X-rays or ultrasound
- Urine analysis
These help identify the underlying cause and rule out serious conditions.
Treatment for Fever in Cats
Treatment depends on the cause:
- For infections: Antibiotics or antiviral medications
- For inflammation or pain: Anti-inflammatory drugs (only prescribed by a vet)
- For dehydration: Fluid therapy
- For unknown causes, the vet may monitor your cat and treat the symptoms
Never give your cat human medications like paracetamol or ibuprofen — they can be fatal to cats.
Home Care Tips for a Cat with Fever
While professional treatment is crucial, here are a few ways you can support your cat at home:
- Ensure fresh water is always available
- Keep them in a quiet, comfortable space
- Offer tasty, soft food to encourage eating
- Monitor temperature if you have a pet thermometer
- Follow all vet instructions carefully
When to See a Vet
Visit your vet immediately if:
- The fever lasts more than 24 hours
- Temperature rises above 104°F (40°C)
- Your cat is not eating or drinking
- Symptoms are getting worse
Timely detection and proper treatment can help avoid major health issues.
Conclusion
Fever in cats is a signal that their body is fighting something. Understanding the symptoms and acting early can make all the difference in your cat’s recovery. If in doubt, always contact your vet — it’s better to be safe when it comes to your feline friend's health.
