That’s why it’s important to know the early signs it’s time you take a cat to the vet.

Why Cats Often Hide Their Illnesses
Before diving into the signs, it helps to understand why cats tend to mask their discomfort. In the wild, showing signs of weakness could make them targets for predators. This instinct remains in domestic cats, making it harder for owners to notice when something is wrong.
That’s why preventive vet visits are just as important as reactive ones. If you’re wondering how often you take a cat to the vet, visit this link: https://kooiii.com/pet-care/how-often-do-you-take-a-cat-to-the-vet/ breaks it down based on age, lifestyle, and health condition.

Sudden Changes in Eating or Drinking Habits
Cats are creatures of habit, so a sudden change in their food or water intake is a major red flag. Eating less or skipping meals could indicate dental issues, infections, or even more serious conditions like kidney disease or cancer. Overeating or drinking more than usual might signal diabetes or hyperthyroidism.
Watch out for:
- Avoiding food altogether for more than 24 hours
- Excessive water consumption
- Drooling while eating or signs of pain
-
Lethargy or Low Energy
Sure, cats love their naps. But if your typically playful kitty suddenly becomes sluggish or uninterested in usual activities, something could be wrong. Lethargy is a common sign in many illnesses ranging from minor infections to chronic diseases.
Act fast if you notice:
- Unwillingness to move or jump
- Sleeping significantly more than usual
- Weakness or collapsing
-
Vomiting or Diarrhea
An occasional hairball is normal, but frequent vomiting or diarrhea is not. These symptoms could be caused by anything from dietary intolerance and parasites to more severe gastrointestinal issues.
Seek veterinary care when:
- Vomiting persists for more than a day
- Diarrhea lasts longer than 48 hours
- There is blood present in vomit or stool
-
Unusual Litter Box Behavior

Cats are typically very clean animals, and any changes in their litter box behavior can indicate distress or health concerns. Urinary tract infections (UTIs), kidney issues, or even arthritis can cause your cat to avoid the litter box.
Common signs to watch:
- Urinating outside the box
- Straining or crying while urinating
- Frequent urination with little output
According to the American Association of Feline Practitioners, urinary tract diseases are a top reason cats are taken to the vet (source).
-
Changes in Grooming Habits
Cats take their grooming seriously. If your cat stops grooming or starts overgrooming, it’s a warning sign.
Possible indicators:
- Matted fur or greasy coat
- Bald patches from excessive licking
- Scratching or biting at their skin
Overgrooming can be linked to allergies, stress, or skin conditions. On the other hand, under-grooming may result from obesity, arthritis, or dental problems that make grooming painful.
-
Behavioral Changes
Is your once-friendly cat suddenly hiding, hissing, or acting out? Behavioral changes often signal pain or discomfort, especially if they occur without any clear environmental trigger.
Noticeable changes include:
- Increased aggression
- Avoidance of people or other pets
- Sudden vocalizations (more meowing or yowling)
-
Bad Breath or Drooling
Dental issues are common in cats but often overlooked. Bad breath, drooling, and reluctance to eat could point to gum disease, tooth infections, or even oral cancer.
Signs that warrant a vet visit:
- Foul-smelling breath
- Swollen or bleeding gums
- Excessive pawing at the mouth
-
Noticeable Weight Gain or Loss
Weight changes should never be ignored. A gradual gain might seem harmless, but it can lead to obesity-related complications like diabetes. On the other hand, sudden weight loss is a major red flag that should prompt an immediate vet visit.
According to the Cornell Feline Health Center, cats can lose up to 75% of their kidney function before symptoms become apparent (source).
