Hey my fellow feline friends! 😻 Happy Sunday! It’s another beautiful day to be alive!

Let’s get right into it. What if I told you there’s a proven framework to help your cat live twice as long—naturally? That’s exactly what Dr. Penny Wood, also known as Dr. Zoolittle, shared during her talk at the Feline Wellness Summit. I think this framework is so important for cat parents to know about, I wanted to make sure you have it.

Now at the beginning of my interview with Penny, she made a point to mention that currently, the average lifespan of an indoor cat is roughly about 15 years. And now there are cats living well into their 20s and even 30. So that’s why she is framing this as a way to “double your cat’s healthy lifespan.”

Penny has spent years studying functional and regenerative medicine for animals, and she’s boiled all that knowledge down into something practical and easy to follow: The 7 Pillars of Animal Longevity.

In today’s newsletter, I’ll share a summary of my biggest takeaways from these 7 pillars, and then tell you how I’m applying her tips with Niko and Milo. If you want to help your cat live longer and thrive, keep reading!

And if you want to listen to the audio of Penny sharing her 7 pillars, just take a listen below…

🐾 The 7 Pillars of Animal Longevity (From Dr. Penny Wood, Dr. Zoolittle)

Dr. Penny Wood has dedicated her career to helping pet parents extend their cats’ healthy years. Instead of just reacting to health issues, she teaches preventative strategies that optimize a cat’s biology for longevity.

Here’s a quick breakdown of her 7 Pillars of Animal Longevity:

1️⃣ Species-Appropriate Nutrition

Cats need the right raw materials to thrive—high-quality animal-based proteins, moisture-rich food, and essential nutrients. Many commercial pet foods don’t align with a cat’s biological needs, which can lead to inflammation, kidney issues, and obesity.

✅ Best practice? A fresh, high-moisture, species-appropriate diet (raw or high-quality wet food) over kibble.

2️⃣ Detoxification: Taking Out the Trash

Toxins build up faster in cats than in humans—23 times faster, in fact. Why?

• They’re smaller, so toxins concentrate more.

• They lick themselves constantly, ingesting environmental chemicals.

• They’re exposed to plastics, pesticides, and processed pet food daily.

✅ Best practice? Support detox pathways with clean food, filtered water, and reducing household toxins.

3️⃣ Microbiome Health: Gut, Skin & Mouth

Cats have microbiomes (colonies of good bacteria) in their gut, mouth, and skin that play a huge role in immunity, digestion, and overall health. Disruptions—like antibiotics or poor diet—can cause long-term health issues.

✅ Best practice? Feed gut-supporting foods, avoid unnecessary antibiotics, and keep oral health in check.

4️⃣ Movement, Exercise & Alignment

Cats need daily movement to stay mobile, strong, and pain-free as they age. Exercise helps prevent obesity, keeps joints healthy, and supports nervous system function.

✅ Best practice? Encourage daily playtime, climbing, stretching, and natural movement.

5️⃣ Natural Environment & Rewilding

In the wild, cats are exposed to sunlight, fresh air, soil bacteria, and grounding (walking on natural earth). Indoor cats miss out on these health benefits.

✅ Best practice? Allow safe access to natural sunlight, fresh air, and “rewild” their environment with plants, natural surfaces, and outdoor time if possible.

6️⃣ Hormone Balance & Spay/Neuter Timing

Early spay/neuter can disrupt hormonal balance, affecting growth, metabolism, and even behavior. Penny discusses alternative methods that allow for sterilization without completely removing hormonal expression.

✅ Best practice? Discuss timing and sterilization options with your vet to make the best long-term choice.

7️⃣ Mental Health & Happiness

A happy cat is a healthy cat. Stress, boredom, and lack of mental stimulation can lead to behavioral issues, health problems, and a shorter lifespan.

✅ Best practice? Provide enrichment, trust-based interactions, puzzle feeders, and socialization to keep your cat mentally engaged.

📽️ My Take: How I’m Applying This with Niko & Milo

When I first learned about these 7 pillars, I realized there were so many simple things I could do to help Niko and Milo live longer, healthier lives.

Here’s what I’ve started changing:

🚰 Filtered Water & Detox Support – I switched from tap water to filtered water in a pet fountain. Since cats are more susceptible to toxins, this is an easy way to reduce their exposure.

🥩 Better Food Choices – I’ve transitioned Niko and Milo to high-quality wet food (Open Farm) to give them the moisture and nutrients they need to thrive. I just started adding this chicken soup for the feline soul which is high in moisture and is a blend of humanely raised chicken, chicken bone broth, pumpkin and carrots.

🎾 Intentional Play & Movement – I used to rely on them entertaining each other, but now I make sure they get 10-15 minutes of focused playtime, twice a day. Their favorite toy? A wand toy from Dezi & Roo.

☀️ Rewilding Their Environment – Since they’re indoor cats, I’m adding more natural elements into their space—things like natural cat grass, a sunbathing spot, and fresh air. I also now have an air purifier to help get rid of those toxins.

🐾 What I Wish I Knew for Mia and Nomar – When Mia was diagnosed with kidney disease, (and even before that, when Nomar was around), I didn’t fully understand the role of inflammation, detox pathways, and hydration. I fed Mia and Nomar only kibble for years before realizing a high-moisture diet would have been better for their overall health.

Now, with Niko and Milo, I’m making these small but powerful changes early to help prevent issues before they start. There is still much more I can be doing, but this is a good start!

The interesting thing is these 7 pillars are also healthy for humans. So eat natural foods, stay hydrated, get rid of those toxins and go outside and play yourself, so that when your cat lives to 30, you’ll be around to take care of them! 😊
