The average life expectancy of a house cat
The life expectancy of a house cat typically falls between 12 and 18 years, with some living into their early 20s. Factors like diet, environment, genetics, and access to veterinary care all play a role in determining how long your feline friend will live.
Indoor cats benefit from protection against many risks that shorten the lives of outdoor cats — such as car accidents, predators, and infectious diseases. As a result, house cats usually outlive their outdoor counterparts by several years.
What influences how long a house cat lives?
1. Indoor environment
Indoor cats live in safer, more controlled environments. They’re less likely to be exposed to toxins, traumatic injuries, and communicable diseases. Even indoor-outdoor cats have a significantly shorter average lifespan than strictly indoor cats.
2. Breed and genetics
Some breeds naturally live longer than others. For instance, Siamese and Burmese cats are known for their longevity. Mixed-breed cats often benefit from genetic diversity, which may reduce the likelihood of inherited conditions.
3. Nutrition and weight management
A cat’s diet has a direct impact on their health. Overfeeding and poor-quality food can lead to obesity, which is linked to diabetes, arthritis, and heart disease — all of which can shorten lifespan.
4. Spaying and neutering
Spayed and neutered cats tend to live longer. These procedures lower the risk of certain cancers and eliminate behaviors that can lead to injuries or infections, such as roaming and fighting.
5. Preventive veterinary care
Routine checkups, vaccinations, parasite prevention, and dental cleanings contribute significantly to a cat’s longevity. Early diagnosis of diseases like hyperthyroidism or chronic kidney disease can greatly improve outcomes.

Common health issues in aging cats
As cats enter their senior years, they may face:
- Chronic kidney disease
- Dental disease
- Hyperthyroidism
- Arthritis
- Cognitive decline
- Vision and hearing loss
Owners should watch for changes in behavior, appetite, grooming habits, or mobility — all potential signs of age-related illness. With early intervention and supportive care, many of these conditions can be managed effectively.
Tips to help your house cat live longer
Here are some practical steps to support a long and healthy life:
- Feed a balanced diet based on your vet’s recommendations
- Keep your cat at a healthy weight
- Maintain a safe indoor environment
- Schedule annual (or biannual for seniors) vet visits
- Offer mental stimulation with toys, scratching posts, and playtime
- Avoid household toxins like lilies, essential oils, and certain medications
- Provide dental care, either through vet cleanings or dental treats
