As a devoted cat parent, you’ve likely observed a change in your cat’s behavior and found yourself wondering: Is my cat sick? Cats are masters at concealing their discomfort, making it difficult to spot illness until it becomes more serious. In this post, we’ll explore the most common signs of illness in cats and offer tips on how to catch them early. Plus, we’ll show you how tracking your cat’s activity with a GPS cat tracker can help you identify potential health issues before they escalate.

1) Change in activity and sleep levels

One of the most noticeable changes when a cat is feeling unwell is a shift in their activity and sleep patterns. Cats tend to be creatures of routine, and any sudden changes in how much they sleep or how active they are should not be overlooked.

If your normally energetic cat suddenly becomes more sedentary, or if your cat who loves to nap seems to be sleeping excessively, it could signal illness. On the other hand, if your cat becomes hyperactive or restless at night, it might be due to discomfort or stress.

Using a GPS cat tracker can help you keep an eye on your cat’s activity levels. For instance, Tractive constantly monitors your cat’s activity and sleep and sends you health alerts if there’s a change in your cat’s behavior that you should be aware of. You can share these insights with your vet, so it’s easier to diagnose potential health issues early.

2) Changes in eating or drinking habits

A sudden change in your cat’s eating or drinking habits can be a red flag. If your cat suddenly stops eating or your if your cat won’t drink water, it may be a sign of an underlying issue such as dental problems, gastrointestinal issues, or even kidney disease.

On the other hand, if your cat suddenly starts drinking a lot of water (polydipsia) or has a sudden increase in hunger (polyphagia), it could indicate diabetes or hyperthyroidism.

3) Lethargy and unexplained fatigue

Cats are naturally curious and playful creatures. If your cat is suddenly lethargic, sleeps more than usual, or seems disinterested in playing or exploring, it could be a sign of illness. This could point to a range of issues, from a simple cold to more serious conditions like anemia or heart disease.

What to look for:

  • Excessive sleeping or hiding
  • Lack of interest in usual activities or toys
  • Difficulty moving or walking

4) Changes in litter box habits

Paying attention to your cat’s litter box habits can give you important insights into their health. Changes in urination or defecation, such as increased or decreased frequency, difficulty urinating, or blood in the urine, are all signs that your cat may be unwell. These issues could indicate a urinary tract infection (UTI), kidney problems, or even feline lower urinary tract disease (FLUTD).

What to look for:

  • More frequent or less frequent urination
  • Straining to urinate or defecate
  • Blood in the urine or stool
  • Diarrhea or constipation

5) Unexplained weight loss or gain

If your cat is losing weight without a change in diet, or gaining weight without overeating, it’s important to get them checked by a veterinarian. Weight loss can indicate issues such as hyperthyroidism, diabetes, or even cancer, while weight gain may point to hormonal imbalances or problems with their metabolism.

What to look for:

  • Noticeable weight loss or gain
  • Visible changes in body shape
  • Increased or decreased appetite without a clear cause

6) Excessive grooming or unkempt coat

Cats are known for their grooming habits, but if you notice that your cat is grooming excessively, it could be a sign of stress, allergies, or skin problems like fleas or dermatitis. On the other hand, if your cat has stopped grooming altogether and their coat appears dull or matted, this may indicate pain, arthritis, or other health concerns.

What to look for:

  • Over-grooming or licking certain areas
  • Lack of grooming and a dull, matted coat
  • Bald spots or skin irritation

7) Coughing, sneezing, or difficulty breathing

Respiratory issues in cats are serious and should be addressed promptly. Coughing, wheezing, or labored breathing could be symptoms of a respiratory infection, asthma, or even heart disease. If your cat is having difficulty breathing or you notice rapid breathing, it is essential to seek immediate veterinary attention.

What to look for:

  • Frequent coughing or sneezing
  • Labored breathing or wheezing
  • Nasal discharge or watery eyes

8) Behavioral changes

Cats are creatures of habit, and any sudden behavioral changes should not be ignored. If your cat is hiding more frequently, becomes aggressive, or shows signs of anxiety or fear, it may be due to pain, stress, or illness. Changes in behavior are often the first sign of discomfort, and identifying the cause early can help prevent more serious complications.

What to look for:

  • Sudden aggression or irritability
  • Hiding more than usual or avoiding interaction
  • Increased anxiety or stress-related behaviors (e.g., excessive scratching)

9) Fever and shivering

If your cat is shivering or has a fever, it’s usually a sign of an infection or inflammation. A fever can be caused by anything from a simple cold to a more serious condition like an abscess, kidney disease, or cancer. If you suspect your cat has a fever, contact your veterinarian for advice.

What to look for:

  • Shivering or trembling
  • Warm or hot ears
  • Decreased activity levels

10) Changes in eyes, nose, or mouth

Changes in your cat’s eyes, nose, or mouth can be indicative of health issues. Watery eyes, squinting, or redness can suggest a respiratory infection, while drooling, bad breath, or difficulty eating could point to dental disease or oral problems.

What to look for:

  • Red, watery, or squinting eyes
  • Excessive drooling or bad breath
  • Difficulty eating or swallowing

When to see a vet

If you notice any of the signs mentioned above, it’s important to consult with a veterinarian. Early diagnosis can make all the difference in your cat’s health and wellbeing. Your vet will conduct a thorough examination, and may recommend tests like blood work, urine analysis, or X-rays to determine the cause of your cat’s symptoms.

Final thoughts

As a responsible cat parent, it’s essential to be vigilant and proactive about your cat’s health. By being aware of the signs of illness and seeking prompt veterinary care, you can help your feline companion live a long, happy, and healthy life. And don’t forget, using a GPS cat tracker and activity monitor can be an invaluable tool in helping you stay on top of any changes in their behavior.

Remember, you know your cat best—if something seems off, don’t hesitate to reach out to your vet for advice!
