The average life expectancy of outdoor cats will not be the same as your house cats.

This is because outdoor cats live and roam outside without restrictions and are not under supervision too. Hence they are at great risk, resulting in their average lifespan reducing to half, and they live shorter lives than house cats.

4. Factors Influencing a Cat’s Life Expectancy

There are many factors that you can find determining the life expectancy of cats. These include nutrition, healthy diet, lifestyle, breed of cats, genetics, and a few more.

Different breeds have different lifespans, and when it comes to nutrition and lifestyle, if not followed properly, your cat may experience obesity and several health issues.

Your cat ages and there are various life stages involved in this aging process, which are full of challenges. Here are the details for you.

6.1. Stage 1 – Kitten

Your kitty is quite new, and you can find them very playful at this stage.

The majority of kittens don’t require much assistance for their bathroom as well as feeding habits, yet if you want to shape their behavior, you should let them socialize, and allow them to play appropriately.

6.1.1. Healthy Diet for Kittens

For your kitten to develop into a big and strong cat, you have to provide them with a diet that is particularly tailored for their growth, as their caloric requirements are high at this stage.

You can also introduce your kittens’ immune system to vaccines namely FVRCP, rabies, and FeLV.

6.2. Stage 2 – Young Adult

In this life stage of your cat, you can notice that their physical growth would have stopped, yet they remain playful and active.

Younger cats will have a drop in their calorie requirements, and their food should be that of an adult cat. You should also ensure that they have a healthy weight to avoid the risk of getting diabetes and arthritis.

6.3. Mature Adult

At this stage, your cat is a mature cat and their playfulness reduces. You might find these mature cats spending most of their time lying.

You might also notice behavioral changes in the way they use their litter boxes and their activities during nighttime.

For instance, older cats who previously used to be active during the day will now be the same during the night and sleep for long hours during the daytime.

6.3.1. Most Prevalent Diseases During This Stage

Problems related to kidney, liver, and dental disease are more prevalent during this stage, and hence their health conditions should be monitored frequently.

6.4. Senior Cats

When your cat reaches this stage, you may find them relaxed. Most senior cats live indoors spending their time resting. If you identify any abnormal changes in your senior cat, consulting your vet is the best option.
