Introduction
Cats have a reputation for being independent and self-reliant creatures, but this doesn’t mean they don’t need our help from time to time. Just like any other animal, cats can become ill or injured, and it’s important to be able to recognize the signs so you can get them the help they need. It can be difficult to tell if your cat is sick, as cats are very good at hiding their pain and discomfort. But with some careful observation, you can learn to spot the subtle clues that something might be wrong.

Overview of Common Signs of Illness in Cats
According to the American Veterinary Medical Association (AVMA), some of the most common signs of illness in cats include changes in eating habits, elimination habits, behavior, grooming habits, fever, and respiratory issues. By learning to recognize these signs, you can help keep your cat healthy and get them the treatment they need as soon as possible.
Benefits of Knowing How to Identify Signs of Illness in Your Cat
The benefits of being able to identify signs of illness in your cat go beyond just knowing when to take them to the vet. By understanding the subtle clues that your cat might be feeling unwell, you can also be proactive about their health and wellbeing. For example, if you notice a change in their appetite or elimination habits, you can take steps to address the issue before it becomes a bigger problem. Additionally, by monitoring your cat’s behavior and looking for changes, you can also detect signs of stress or anxiety that may require intervention.
Observing Changes in Eating Habits
One of the easiest ways to tell if your cat is unwell is to observe changes in their eating habits. A sudden decrease in appetite can be a sign of illness, as can changes in food preferences. Here are some things to look out for:
Noticing Reduced Appetite
If your cat suddenly stops eating or is no longer interested in their food, this could be a sign of an underlying health issue. According to the AVMA, cats who are feeling unwell often lose their appetite, so it’s important to pay attention to changes in eating habits. If your cat stops eating entirely, it’s best to contact your veterinarian right away.
Monitoring Food Intake
In addition to observing changes in appetite, it’s also important to monitor your cat’s food intake. If your cat is eating normally but not finishing their meals, this could be a sign of an underlying issue. You may also want to take note of how much your cat is eating compared to their usual amount, as this could be an indication that something is wrong.
Looking for Changes in Food Preferences
Cats can be finicky eaters, so it’s important to pay attention to any changes in their food preferences. If your cat suddenly begins avoiding certain foods, this could be a sign of illness. Additionally, if your cat starts eating more than usual, this could also indicate a health problem. Paying attention to your cat’s eating habits can help you detect potential issues early on.
Monitoring Your Cat’s Elimination Habits
Changes in your cat’s elimination habits can also be a sign of illness. If your cat is having difficulty urinating or defecating, this could indicate a urinary tract infection or another type of health issue. Here are some things to look out for:
Noticing Changes in Urination Habits
If your cat is having difficulty urinating or is producing unusually large amounts of urine, this could be a sign of a urinary tract infection or other health issue. Additionally, if you notice blood in your cat’s urine, this could also indicate a serious problem and should be addressed immediately.
Checking for Diarrhea or Constipation
Diarrhea and constipation can both be signs of illness in cats. If your cat is experiencing either of these issues, it’s important to take them to the vet right away. Additionally, if you notice any changes in the color or consistency of your cat’s stool, this could also indicate an underlying health issue.
Noticing Behavioral Changes
Cats are usually quite active and curious creatures, so any changes in behavior can be a sign that something is wrong. Here are some things to look out for:
Becoming More or Less Active
If your cat suddenly starts sleeping more than usual or becomes less active than they were previously, this could indicate an underlying health issue. Additionally, if your cat is showing signs of restlessness or agitation, this could also be a sign that something is wrong. Paying attention to your cat’s activity level can help you detect potential issues early on.
Becoming More Vocal
Cats are usually quite quiet animals, so if your cat is meowing or yowling more than usual, this could indicate that they are in pain or discomfort. Additionally, cats who are feeling unwell may become more vocal in order to get attention, so it’s important to pay attention to any changes in vocalization.
Showing Signs of Stress or Anxiety
Stress and anxiety can also be signs that something is wrong. If your cat is exhibiting signs of stress, such as excessive grooming, hiding, or aggressive behavior, it’s important to take them to the vet to rule out any underlying medical issues. Additionally, if your cat seems anxious or fearful, it’s important to consult a veterinarian to determine the cause.
Checking for Signs of Pain or Discomfort
If your cat is in pain or discomfort, there are several signs to look out for. Here are some of the most common signs:
Limping or Refusing to Walk
If your cat is limping or refusing to walk, this could indicate an injury or an underlying medical condition. Additionally, if your cat is favoring one side or appears to be in pain when walking, this could also be a sign of an underlying issue.
Refusing to Be Touched or Picked Up
Cats usually love being petted and cuddled, so if your cat is resistant to being touched or picked up, this could be a sign that something is wrong. Additionally, if your cat hisses or growls when touched, this could also be a sign of pain or discomfort.
Acting Aggressively When Touched
Cats who are in pain or discomfort may also act aggressively when touched. If your cat is swatting or biting when touched, this could indicate that something is wrong and should be addressed immediately.

Looking for Changes in Grooming Habits
Cats are usually quite fastidious groomers, so any changes in grooming habits can be a sign of illness. Here are some things to look out for:
Noticing Excessive Licking or Chewing
If your cat is excessively licking or chewing on themselves, this could be a sign of an allergy or skin infection. Additionally, if your cat is grooming areas of their body that they usually don’t, this could also indicate a health issue. Paying attention to your cat’s grooming habits can help you detect potential problems early on.
Observing Hair Loss or Bald Patches
Hair loss or bald patches can also be a sign of illness. If your cat is losing large amounts of fur or has patches of missing fur, this could indicate a skin infection or other health issue. Additionally, if your cat is excessively scratching or biting at their fur, this could also be a sign of an underlying problem.

Watching for Signs of Fever or Respiratory Issues
Fever and respiratory issues can also be signs of illness in cats. Here are some things to look out for:
Noticing Increased Temperature
If your cat has a fever, their temperature will be higher than usual. To check your cat’s temperature, use a digital thermometer and insert it into their rectum. If their temperature is over 103 degrees Fahrenheit, this could indicate a fever and should be addressed immediately.
Listening for Wheezing or Coughing
Wheezing or coughing can also be signs of respiratory issues. If your cat is having difficulty breathing or is making unusual noises when breathing, this could indicate an underlying issue and should be addressed immediately. Additionally, if your cat is having difficulty swallowing, this could also be a sign of an underlying health problem.
Conclusion
It can be difficult to tell if your cat is sick, as cats are very good at hiding their pain and discomfort. However, by paying attention to changes in eating habits, elimination habits, behavior, grooming habits, fever, and respiratory issues, you can help detect potential health issues early on. Additionally, by monitoring your cat’s activity level and looking for signs of stress or anxiety, you can also be proactive about their health and wellbeing.
Summary
Cats are very good at hiding their pain and discomfort, but there are several signs you can look for to tell if your cat is unwell. These include changes in eating habits, elimination habits, behavior, grooming habits, fever, and respiratory issues. By learning to recognize these signs, you can help keep your cat healthy and get them the treatment they need as soon as possible.
