《Alex Chen｜Formulator’s Lab Notes》
About the Author: I’m Alex Chen—Lead Formulator & Grooming Specialist. I split my life between San Francisco, where I work with real pets and real skin issues every day, and Taipei, where I collaborate with labs that treat manufacturing like a medical discipline. I don't believe in marketing fluff; I believe in data, transparent chemistry, and the honest feedback a pet's skin gives us.

I was scrolling through a fascinating thread on Quora recently: Do cats know what we are? Do they think we're some kind of big cat? Or just a very weird creature giving them food?
According to prominent anthrozoologists, cats don't alter their social behavior around us the way dogs do. When a cat rubs against your leg, kneads your stomach, or grooms your hair, they are treating you exactly how they treat other cats. In their minds, we aren't "masters." We are just giant, somewhat clumsy, non-hostile cats who happen to be excellent at opening cans.
When I look at my rescue Calico, Miso, and realize she just sees me as a massive, hairless roommate, the formulator in me immediately starts analyzing the variables. If I am a "giant cat" to her, how am I presenting myself biologically and chemically?
Let’s look at the chemistry for a second. If we are giant cats, we are doing a terrible job at smelling like them.
The Chemical Alien in the Living Room
Think about how a mother cat grooms her kittens. She uses a rough tongue and saliva. It’s a purely mechanical and enzymatic process with absolutely zero artificial fragrance.
Now, look at how humans try to show affection. We wash our floors with citrus-scented cleaners. We use lavender essential oil diffusers. We bathe our pets in shampoos loaded with synthetic foaming agents and heavy perfumes because we think it smells "clean."
To a cat, this isn't clean. It's terrifying.
Cats lack the UGT (UDP-glucuronosyltransferase) liver enzyme required to break down many of these compounds. When you, the "giant cat," approach them smelling like a synthetic lavender field, you aren't just offending their highly sensitive olfactory receptors—you are introducing a metabolic threat. You become a chemical alien.
Biomimicry and the Taiwan "Ding-Jin" (頂真)
This realization completely shifted how I approach feline product development. If cats treat us like their own kind, our grooming products need to respect their biological reality.
When I flew back to Taipei to develop our Mooncat line, I rejected over 50 "industry standard" formulas. They were too loud, too fragrant, and too focused on pleasing the human buyer. I had to tap into that Taiwanese "Ding-Jin" (頂真)—an obsessive, uncompromising dedication to doing things the right way, even if it's harder.
We stripped everything down. We started with medical-grade RO (Reverse Osmosis) Purified Water, completely rejecting tap water that contains hard minerals that disrupt the skin barrier. We formulated to a precise feline level, and most importantly, we adopted a strict "scent-neutral" philosophy.
The Living Room Test
I don't formulate for the bottle; I formulate for the skin. And more importantly, I formulate for the bond between you and your cat.
Every batch we make has to pass my Living Room Test with Miso. If I wipe her down with our Mooncat wipes and she immediately runs away to aggressively lick herself clean, the formula fails. She should feel like she was just groomed by another cat—safe, neutral, and unbothered.
If your cat thinks you are a giant cat, do them a favor: stop smelling like a toxic human. Data doesn't lie, but your cat's behavior tells the real story.
🔬 Scientist's Note & Groomer's Tip
Groomer's Tip: Want to bond with your cat using their own language? Mimic a mother cat's grooming. Instead of full-body baths which cause immense stress, use a warm, damp, scent-free wipe (ideally using RO water) and gently stroke them around the face, cheeks, and behind the ears. These are the areas where cats have scent glands and where they groom each other to show affection.
Scientist's Note: Never use products containing citrus (d-limonene), tea tree, eucalyptus, or peppermint around your cats. While these are marketed as "natural" and "fresh" in human products, they are hepatotoxic (liver-toxic) to felines. "Natural" does not always mean safe. Lab-verified, species-specific chemistry is what guarantees safety.
💬 Ask Alex Anything (Q&A)
Q: Why does my cat bite my ankles or run away right after I take a shower? Alex: You just washed off your familiar, comforting scent and replaced it with a blast of synthetic body wash and shampoo. To your cat, the "giant cat" they trust just disappeared, and a stranger smelling of artificial coconuts and harsh surfactants just walked into the room. It causes sensory confusion. Give them time to recognize your baseline scent again.
Q: Do cats actually need to be bathed with shampoo? Alex: Rarely. Healthy cats are meticulous groomers. Unless they have gotten into something toxic, have a severe flea infestation, or are hairless breeds (like Sphynx) that require oil management, a full water bath is usually unnecessary and highly stressful. For routine maintenance, targeted wiping with a pure, unscented, feline-safe wipe is far superior to stripping their coat with a 50:1 diluted commercial shampoo.
Q: Why does my cat rub its face on my laptop or my shoes? Alex: They are marking you with their pheromones. Cats have scent glands on their cheeks and chin. By rubbing against your heavily used items, they are mixing their scent with yours, essentially claiming you as part of their family group. It’s the ultimate compliment from a cat—they are making sure the "giant cat" smells like they belong to the same tribe.
