Cats already have 9 lives, but what if we could give them 18? Longevity research isn’t just benefiting humans: I looked into some supplements and products that may help you extend your cat’s lifespan, or at least their healthspan.

If you proudly share a house or apartment with one or more cats, chances are you want your precious pet to live a long and healthy life. In addition to getting the basics of diet, exercise, and safety right (basically, do the opposite of the cartoon Garfield), there are many cat longevity products out there that aim to increase your cat’s lifespan.

We’ve taken the time to explore some of them, and this comprehensive list of the top nine cat longevity products is a resource you can use to discover options that may keep that furry feline of yours not only healthy but also happy, energetic, and curious for many years to come.

Our list features cat nutrition products, including longevity cat food and joint care for cats products, as well as cat supplements, and some more unconventional cat health products like pet insurance. As always, we are highlighting high-quality, science-backed products that generally have research showing at least healthspan-, if not lifespan-, extending effects.

Looking for some good holiday reads? We’ve updated our list of best longevity books and added several from top longevity researchers like Dr. Harold Katcher, Dr. Morgan Levine, and Dr. Peter Attia.

Update 11/7/2023: This post has been updated since we originally published it in September 2020 and first updated it in April 2021. Several new best longevity books have been added to both the main list and honorable mentions sections, and the post has been cleaned up, and review ratings made current.

There are a lot of life extension and longevity books published every year.

A. Lot.

We interviewed four longevity experts (including several Lifeboat Foundation board members) to learn how they think about their diets. I was particularly struck by how different they all were (except almost all of them fasted)!

Food.

In all our research into longevity so far, from quantifying how we sleep to exploring the science behind whether human life extension is possible, nutrition has remained the most controversial and confusing subject that we’ve covered. For example, when we surveyed 101 of our readers on their longevity diet, we got 101 very different answers. There is little consensus on what the perfect life extension diet should look like.

I know some epidemiological studies have promoted moderate alcohol intake as better for longevity than not drinking at all, but I thought that sounded kinda suspicious, so I dug into all the research to see for myself.

Turns out, there’s actually some in vivo studies showing life extension effects of low amounts of alcohol on animals.

What’s the effect of moderate alcohol on life expectancy? The science is confusing so we did a deep dive to find if a little booze is healthy.

I could find hardly any scientific studies that showed negative results from the Mediterranean Diet for longevity, which honestly makes me a little wary of scientific establishment groupthink.

That said, I think I am going to start taking shots of olive oil after all my research…

Is the Mediterranean Diet the key to longevity? Lots of research suggests olive oil and other Mediterranean foods can help you live longer.

We’ve updated our list of top longevity conferences and events for 2021, adding 4 new ones and removing 3 that are no longer happening:

Update 5/10/2021: This post has been updated since we originally published it in August 2020. Several new longevity conferences have been added and several which are no longer happening have been removed.

Usually, when you approach a random stranger and immediately begin talking about things like DNA methylation rates and NAD+ precursors, you’re lucky if all you get is a weird look.

Can low-carb diets like Keto help you live longer? I spent way too much time reading research papers and the answer seems to be…maybe.

I love bacon.

On a beach trip with some college friends a few years ago, I was put in charge of breakfast. I made sure to buy eight pounds of bacon (one for every person on the trip) for our three days at the beach house.

Scientists don’t actually agree on why we age (which I find a little wild), but there are a number of competing theories of aging.

I dug into 4 of the most representative and current. Any ones you’d add?:

Why do we age? Lots of theories have tried to explain the aging process, but the truth is scientists still don’t agree on a single reason.

Some really cool advances happening in cancer detection with things like liquid biopsies from companies like Grail and Thrive:

It’s important to detect cancer early to maximize longevity and survival rates. Here are cancer screening tests for 6 deadly cancers.

Bitcoin mining is mainly driven by renewable energy — hydro (by far the largest component), solar, wind and geothermal. Period.

In fact, we’ve estimated the lower bound of renewables penetration in the bitcoin mining energy mix to be 77.6%.

From 2018, but it’s likely gotten better since then.
