Essential Oils, Babies & Pets: What You Need to Know Before You Apply
A guide for every household with a curious cat, a licking dog, or a little one with delicate skin.
One of the most common questions we get at the farmers market — right after "does it smell like beef?" — is some version of this:
"Is it safe around my cat?"
"Can I use it on my baby?"
"My dog licked my arm after I put it on — is that okay?"
These are good questions. Important ones. And the answers are more nuanced than most skincare brands will tell you — because most skincare brands aren't thinking about your cat when they formulate their products.
We are.
Let's Start With Babies
Babies are not small adults. Their skin is thinner, more permeable, and more absorbent than adult skin. Their detoxification pathways are immature. Their immune systems are still developing. What is perfectly safe for you can be too much for them.
Our position on babies is simple: No Bull. Always.
Our No Bull line — body balm, lotion bar, lip balm — contains zero essential oils. Zero fragrance of any kind. Just grass-fed tallow, organic botanical oils, beeswax, and arrowroot. The cleanest possible formula.
Essential oils — even high quality, pure, therapeutic grade essential oils — are powerful plant medicine. They work because they're bioactive. And that bioactivity is exactly why they're not appropriate for newborns and young infants. Their bodies aren't equipped to process the chemical compounds efficiently, and the risk of sensitization — developing a lasting allergic response to an ingredient through early exposure — is real.
Our recommendation:
- Newborns and infants — No Bull only, always
- Toddlers and young children — use discretion. Some gentle essential oils at appropriate dilution may be fine, but always introduce slowly and patch test. When in doubt, No Bull
- Older children — our scented products are generally appropriate, but always patch test before widespread use
The good news: our No Bull products work beautifully for babies. Many of our customers use the unscented body balm for baby eczema, diaper rash, cradle cap, and general dry skin. It's pure enough for the most delicate skin on earth.
Now Let's Talk About Cats
This is the one that really matters — because cats are uniquely, specifically, and significantly vulnerable to essential oils in a way that dogs are not.
Cats lack glucuronyl transferase — the liver enzyme responsible for metabolizing phenols, terpenes, and ketones found in most essential oils. This isn't a minor difference. Cats lack an essential enzyme in their liver and as such have difficulty metabolizing and eliminating certain toxins like essential oils. The toxic compounds build up in their bloodstream rather than being safely eliminated — and the effects can range from respiratory irritation to liver failure.
Both ingestion and skin exposure can be toxic. Essential oils and liquid potpourris contain chemicals that are rapidly absorbed orally or through the skin. Only a few licks or a small amount on the skin could be harmful, depending on the ingredients and how the cat is exposed.
This matters for Magnolia Crow customers because of something that happens constantly at the farmers market: someone asks if their cat can be in the room when they apply their balm — or mentions their cat licked their arm after they moisturized.
Here's the honest answer: it depends on which product, how much, and your cat.
The oils in our scented products most relevant to cats:
Our Mountain Spa blend contains lavender, tea tree, and lemon. Essential oils that are known to cause poisoning in cats include oil of wintergreen, oil of sweet birch, citrus oil, pine oils, ylang ylang oil, peppermint oil, cinnamon oil, pennyroyal oil, clove oil, eucalyptus oil, and tea tree oil.
Tea tree and citrus are in some of our blends. This doesn't mean our products are dangerous to cats — the concentration of essential oils in a finished balm is a tiny fraction of the total formula, and the amount that might transfer from your skin to a cat who licks your arm is tinier still. But it does mean we take it seriously and want you to be informed.
The math matters here:
Our body balm is formulated at a safe skin dilution for humans — well under 3% total essential oil content by weight in a 4oz jar. The amount of essential oil in a single application is a fraction of a gram. The amount that might transfer to a cat who licks your arm after application is smaller still — parts per thousand of an already small amount.
That said: cats are expert self-groomers, and if they lick essential oil residue off their skin, it can poison them. Accumulated exposure over time matters, and some cats are more sensitive than others.
Our recommendations for cat households:
- Use No Bull unscented products if your cat regularly licks you or sleeps on you
- If using scented products, allow them to fully absorb before contact with your cat — this takes just minutes with our formula
- Never apply any scented product directly to your cat — ever, for any reason
- Keep product jars stored away from curious cats — concentrated essential oils are a different risk level than applied-to-skin products
- If your cat shows any signs of drooling, wobbling, lethargy, or respiratory distress after exposure, contact your vet immediately
We use only high quality, pure essential oils in our formulas — no synthetic fragrance, no fragrance compounds, no mystery ingredients. The quality of the oil matters. But quality doesn't eliminate the cat concern — it just means what's in our products is exactly what we say it is.
How long until it's safe?
Our tallow balm absorbs significantly faster than conventional lotions — usually within 2-5 minutes of application for most people. You'll know it's absorbed when your skin no longer feels tacky or oily to the touch.
For cat households we recommend waiting the full absorption time plus a few extra minutes before allowing contact — cats are thorough groomers and will find residue you didn't know was there. A good rule of thumb: apply, go do something else for 5-10 minutes, then resume cuddle time.
Essential oils NEVER safe to diffuse around cats:
- Tea tree (melaleuca) — one of the most dangerous, even in small amounts
- Peppermint
- Eucalyptus
- Citrus oils (lemon, orange, grapefruit, bergamot, lime)
- Ylang ylang
- Cinnamon
- Clove
- Pine
- Wintergreen
- Sweet birch
- Pennyroyal
- Thyme
- Oregano
- Lavender — commonly believed to be safe but classified as mild-to-moderately toxic by veterinary toxicologists
This is not an exhaustive list. When in doubt, don't diffuse around cats. If you do use a diffuser, always ensure your cat can leave the room freely and the space is well ventilated.
What About Dogs?
Dogs are more resilient than cats when it comes to essential oils — their livers metabolize these compounds more efficiently — but they're not immune to concern.
Tea tree, wintergreen, pine, cinnamon, citrus, eucalyptus, peppermint, and ylang ylang oils are toxic to dogs. Several of these appear in our scented blends at appropriate skin-safe dilutions. The same math applies as with cats — the concentration at skin level after application is very low — but dogs who lick enthusiastically and repeatedly warrant attention.
The good news for dog households: cautiously safe options for dogs include lavender, frankincense, and chamomile in well-ventilated rooms. Our Mountain Fleur blend contains ylang ylang which warrants more caution around dogs.
Our recommendations for dog households:
- Most of our products are fine in dog households with normal use
- Allow products to fully absorb before your dog licks your skin
- For dogs who are serious lickers — consider No Bull for your daily moisturizer and save the scented products for when you'll have a few minutes without canine assistance
- Our unscented Tallow Lotion Bar is safe and wonderful for dogs — many of our customers use it on dry dog noses and cracked paw pads. Grass-fed tallow is nourishing, paw-friendly, and completely safe if licked
Never apply any product containing essential oils directly to your dog's skin without veterinary guidance — what's safe for human skin at human dilutions may not be appropriate for direct animal application.
How long until it's safe?
Our tallow balm absorbs significantly faster than conventional lotions — usually within 2-5 minutes of application for most people. You'll know it's absorbed when your skin no longer feels tacky or oily to the touch.
For dogs — particularly enthusiastic lickers — the same window applies. 5-10 minutes after full absorption is absorbed is a reasonable buffer. If your dog is a dedicated arm-licker, consider applying your balm before an activity that naturally keeps them occupied — a walk, feeding time, or a chew — to allow full absorption before the licking resumes.
Essential oils NEVER safe to diffuse around dogs:
- Tea tree (melaleuca)
- Wintergreen
- Pine
- Cinnamon
- Citrus oils (lemon, orange, grapefruit, lime)
- Eucalyptus
- Peppermint
- Ylang ylang
- Pennyroyal
- Sweet birch
- Clove
- Anise
Dogs are more tolerant than cats but still vulnerable. Lavender, frankincense, and chamomile are generally considered cautiously acceptable for diffusion in well-ventilated rooms where dogs can freely leave. Always monitor for signs of irritation.
The No Bull Promise
For every member of your household — human, feline, canine, or small and new to the world — our No Bull unscented line is the answer. Pure grass-fed tallow, organic botanicals, beeswax, and arrowroot. Nothing that requires a safety conversation.
It's what we'd reach for first in any household with babies, cats, or dogs who love to lick. And it works beautifully — because the tallow does the heavy lifting, and it doesn't need any help from essential oils to nourish and protect your skin.
