How Do Cats Age?

There are four primary factors involved in determining how old your cat will become. They are genetics, environment, health, and activity level. Let’s take a look at each of these factors and what they mean for your cat’s health. If you want to know why your cat is getting older, read on! You might be surprised at what you discover! Whether it’s age-related problems or a healthy aging process, your cat is likely to age like a member of the family.


One study found that cats’ methylation patterns were associated with aging. Using chromatin state analysis, the researchers found that age-associated methylation changes were associated with bivalent chromatin domains (TSSs) and PAX4 binding sites. These changes are related to the regulation of mitophagy and telomerase, two processes implicated in feline aging. However, more studies are needed to determine which CpGs are involved.

Researchers believe that the genes involved in cat aging have a clock-like function derived from the evolutionarily conserved DNA sequences. Because these clocks are shared, they are useful in predicting the age of individuals of the same species. These clocks are called epigenetic age, and they are not fully understood. However, cross-species studies of epigenetic aging are likely to stimulate future research.

Activity level

Cats’ activity level changes as they get older, but the main causes may not be obvious. Cats can be solitary or interactive, and their exercise may come in the form of hunting, foraging, exploring, or patrolling. However, gentle playtime is the best regimen for an elderly cat. For example, you can buy a large self-play toy for your older cat. This will encourage it to grab and play, and will provide a wide range of motion exercises.

Interestingly, the activity level of cats remained similar between male and female cats. However, female cats were significantly more active before they were spayed. Female cats had similar daily physical activity levels before they were spayed. The findings from this study suggest that aging reduces physical activity in cats. Consequently, older cats may have increased FAA. The research team hopes to make a better estimate of an aging cat’s activity level in the coming years.


Aging cats are more likely to develop various health issues, affecting the way they live, work, and play. Aging cats have poorer immune systems due to the chronic diseases associated with the process. Additionally, dehydration further reduces blood circulation and immune system. In addition, the skin becomes thinner, less elastic, and more vulnerable to infection and injury. In addition, the body loses muscle mass and becomes more prone to anxiety and depression.

Older cats are more likely to suffer from degenerative joint disease, a painful condition that can cause organ failure and cause thromboembolic events. They may also have difficulty accessing their food and litter box, and may not be as active as they once were. Other diseases associated with old age include diabetes and hypertension. These conditions can be treated easily if detected early. Finally, there are many possible causes of degenerative joint disease in older cats.
