《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.

If you want to divide a room instantly, just ask the question I recently saw trending on Quora: Are you a dog person or a cat person?
The answers are passionate, deeply personal, and highly revealing. People usually answer based on their emotional needs. But as a biotech formulator, when I read these answers, I don't just see personality traits—I see distinct biological profiles. The reasons we love them are the exact reasons we must formulate for them differently.
I selected three of the top-voted perspectives from that Quora thread. Let’s look at the chemistry behind the personalities.
Quote 1: The Dog Person's Perspective
"I am 100% a dog person. Dogs give you unconditional love. They force you to get off the couch, go outside, and experience the world. Yes, they get muddy and smelly, but the sheer joy they show when you walk through the door is worth every bit of the mess."
Alex’s Formulator Commentary: This user perfectly described the "Active/Loyal Biology." Dogs are pack animals that interact with the world through physical immersion. They run, they sweat (through their paws), and their sebum mixes with outdoor bacteria, creating that distinct "wet dog smell."
Because they offer unconditional love, they are eager to please. If you put them in a tub and scrub them with a cheap, heavily perfumed shampoo, they will tolerate it because they trust you. This is where the industry takes advantage of them.
When we formulated the Arf Arf line in Taipei, we knew we couldn't betray that trust. A dog's skin sits at a golden of 7.2. If you use a human-grade shampoo ( 5.5), you are stripping their barrier. To handle the "muddy and smelly" reality this Quora user loves, we don't use masking perfumes. We use Taiwan Patent I718069—a physical compound structure that locks and neutralizes odor molecules at the source. We let dogs be active, but we clean them with medical-grade precision.
Quote 2: The Cat Person's Perspective
"Cat person here. Cats teach you about boundaries and consent. They are fastidious, independent, and quiet. They don't need constant validation. When a cat chooses to sit on your lap and purr, it feels like a privilege because you had to earn their respect."
Alex’s Formulator Commentary: This is the "Boundary/Fastidious Biology." Cats are apex predators and meticulous self-groomers. They don't get "muddy" like dogs, but they present a much more complex chemical challenge.
Earning a cat's respect means respecting their metabolic limits. Cats lack the UGT (UDP-glucuronosyltransferase) liver enzyme. They cannot process the synthetic fragrances and essential oils that humans love. When a cat person says their pet is "fastidious," it means the cat will lick off whatever you put on their coat.
If you use a citrus-scented wipe on a cat, you are violating their consent and poisoning their liver. For our Mooncat feline line, we apply the Taiwanese "Ding-Jin" (頂真)—an uncompromising meticulousness. We practice subtractive chemistry. We use RO (Reverse Osmosis) Purified Water and strictly enforce my 30-Centimeter Rule: zero detectable scent. You earn a cat's privilege by keeping their chemical environment completely silent.
Quote 3: The "Bi-Petual" (Both) Perspective
"I have both, and they are just different. My dog is like a toddler—he needs constant attention and direction. My cat is like a teenager—she hangs out in her own space and comes down for affection on her own terms. You just have to adapt to their different vibes."
Alex’s Formulator Commentary: The "Hybrid Household" is the ultimate test of a pet parent's discipline. Adapting to their "different vibes" isn't just about giving the dog a walk and the cat a scratching post; it’s about strict chemical separation.
You cannot use the same grooming products on both. A high-quality dog shampoo, perfectly balanced to 7.2 with safe botanical odor-neutralizers, can be toxic to a cat's UGT-deficient liver if the cat grooms the dog, or if you use the same towel. In a hybrid home, the dog gets the targeted odor-neutralizing baths, and the cat gets the scentless, RO-water wipes.
The Living Room Test
Whether you are a dog person, a cat person, or both, the rule remains the same. My Shiba Inu, Bento, and my Calico, Miso, have completely different personalities and completely different biologies. But they both deserve products that pass the Living Room Test: safe, transparent, and biologically appropriate. Data doesn't lie, but how your pet reacts to your touch tells the real story.
🔬 Scientist's Note & Groomer's Tip
Groomer's Tip: If you live in a multi-pet household (dogs and cats), never share grooming tools without washing them first. If you brush your dog with a slicker brush after a bath using a scented dog shampoo, and then use that same brush on your cat, you are transferring synthetic compounds and dog sebum directly onto the cat's coat. The cat will immediately try to groom it off, ingesting those compounds. Keep a separate, color-coded brush for each species.
Scientist's Note: Why is mixing up products so dangerous? It comes down to the logarithmic nature of the scale. A difference of 1.0 on the scale means a tenfold increase or decrease in acidity. A dog's skin ( ~7.2) is significantly more alkaline than a cat's skin ( ~6.0-6.5), and vastly different from human skin ( ~5.5). Using a "one-size-fits-all" pet shampoo guarantees that at least one of your pets is suffering from chronic acid mantle disruption.
💬 Ask Alex Anything (Q&A)
Q: I am a dog person, but my dog hates baths. Can I just use cat wipes on him? Alex: You can, as our Mooncat wipes are incredibly pure (RO water, zero scent), so they won't harm your dog. However, they won't be very effective for odor control. Dogs produce a different type of sebum and sweat than cats, which requires specific odor-neutralizing technology (like our Arf Arf line) to break down. A cat wipe will remove surface dirt, but the "dog smell" will remain.
Q: I am a cat person. My cat smells like my dog because they sleep together. Should I bathe the cat? Alex: No. Do not bathe the cat. If the cat smells like the dog, the solution is to improve the dog's hygiene routine, not to stress the cat with a water bath. Ensure you are using a scientifically formulated, odor-neutralizing shampoo on the dog. If the cat has dog saliva or oil on its coat, simply wipe the cat down with a pure, unscented RO-water wipe to physically remove the residue.
Q: Why do dog products always smell so strong, while cat products are usually unscented? Alex: Because the industry formulates for the human buyer, not the animal. Dog owners complain about "wet dog smell," so cheap brands pump formulas full of artificial fragrances to mask it. Cat owners complain less about cat body odor (since cats self-groom), so the products are milder. However, neither animal should be subjected to heavy perfumes. True clean smells like nothing.
