Because cats are quirky (and they sometimes take a bit of time to warm up to people) it can be difficult to tell whether they’re sick, moody, or just being cats. Use this checklist as a starting point for determining whether your cat has a good bill of health.

Among pet parents, there are two questions we hear over and over again: ‘How can I tell that my cat (or dog) is healthy’, and ‘how can I tell if my pet is happy?’

Because cats are quirky (and they sometimes take a bit of time to warm up to people) it can be difficult to tell whether they’re sick, moody, or just being cats. Use this checklist as a starting point for determining whether your cat has a good bill of health. 

But, remember, this list is just for reference and is by no means exhaustive or personalized based on your pet’s needs. You should always consult your Parker & Ace veterinarian around your pet’s health and wellness—especially if you have concerns about something specific.  

How to tell if your cat is healthy

Vaccinations Up to Date


The most important thing you can do for your cat’s health is to ensure they have been fully vaccinated. Cats should be vaccinated against rabies, feline leukemia, immunodeficiency viruses, and more. Your cat should also be on heartworm, tick, and flea medications to prevent contractible diseases and infestations. If you’re unsure whether your cat is/was properly vaccinated, get in touch with your Parker & Ace vet team today.

Proper Diet and Weight


Your cat should eat regularly and exercise at least moderately. Your cat shouldn’t have a saggy belly nor should their ribs be clearly visible through their skin. There is no perfect weight for a cat, but if yours rapidly drops or puts on weight, there may be something amiss.

Proper Breathing


When your cat breathes, it shouldn’t be raspy, ragged, fast, or strained. Cats generally breathe around 20-40 times a minute, but that number varies cat-by-cat. Spend time getting to know how your cat breathes normally so you can easily notice any sudden breathing changes.

Normal Heart Rate

Like breathing, your cat’s heart rate is unique to their body—a normal heart rate for a cat tends to be between 140 to 220 beats per minute. Of course, with a new exercise regimen, more (or less) activity, and even with age, their heart rate can quicken or decrease.

Clean, Healthy Teeth

You may not be in the habit of looking in your cat’s mouth, but this is something worthwhile to check routinely if they allow. Monitoring is also important; as a general rule, if they are eating and behaving normally and regularly visiting the vet for checkups, there is less of a chance of a major issue.. However, if you notice bad breath, trouble (or noises) while chewing, or visibly broken or cracked teeth, make sure to get in touch with your Parker & Ace vet team immediately. Signs of general malaise or irritableness can also be signs of dental discomfort. Being proactive with cleaning or using water additives may help reduce plaque accumulation over time.

Healthy Eyes

Your cat’s eyes should be clear and free of any discharge. If you notice bloodshot eyes or a “third eyelid” (a white film over the eyeballs), contact your Parker & Ace vet team.

No parasites

Visible parasites—mites, fleas, ticks, worms, etc.—are a definite cause for concern and necessitate a call with your Parker & Ace veterinarian. Signs of an infestation include dandruff, shaking of the head, scratching of the ears, and red welts on the skin or bald patches in their fur.

Healthy Fur

Healthy cat fur is thick and without unexplained bald spots. Healthy cats shed regularly, particularly in spring and fall, but excessive or heavy shedding might be a sign of disease. If their fur is getting matted or you see an excessive amount of dandruff, this could be a sign of decreased grooming, which could be from discomfort, being overweight, or internal illness.

Behavior and Behavioral Changes

Behavioral changes can be a sign of illness. Look for things like gradual or sudden lethargy, ravenous appetite, sudden meowing or vocalization that is different or more frequent than normal.

These guidelines can help you keep tabs on some of the most noticeable signs of health in your cat. Rest assured, the Parker & Ace vet team is here to answer any questions you may have—and to ensure your pet is having the happiest and healthiest life ever.
