"She was throwing up every other day and her stool was always off. Two weeks on Catsen — no more vomiting, firm stool, and her coat is shinier than it's been in years. "

A Single Tick Can Lay 3,000 Eggs. And That's Not Even the Worst Part.

The real danger isn't the bite — it's what fleas and ticks carry.

Cat-borne illnesses like Bartonellosis, Cytauxzoonosis, and feline anemia can cost thousands at the vet, and in some cases, your cat's life.

Even indoor cats aren't safe. Fleas and ticks hitchhike in on shoes, clothing, and other pets — all year round.

The First Flea & Tick Pendant Designed for Cats

Here's something almost no one talks about: most "natural" flea and tick collars on the market were designed for dogs first. The "cat version" is usually the same formula, just resized and relabeled.

 

But a cat's liver doesn't work like a dog's. It can't break down the phenols found in many essential oils — and over time, those compounds build up to toxic levels.

 

Tea tree, eucalyptus, peppermint, pennyroyal — all common in "natural" pet collars, all linked to seizures and liver damage, when used on cats.

 

Catwise was built from scratch with this in mind. Every ingredient was screened against feline biology first, then formulated to repel fleas and ticks safely.

How Catwise Works — Set It and Forget It.

Clip It On

Attach the pendant to your cat's collar in seconds. No pills. No drops. No skin contact.

It Activates Naturally

A cat-safe formula releases gradually into the air around your cat — creating an invisible shield that fleas, ticks, and biting insects can't stand.

Protected for 12 Months

One pendant. One year. No monthly reminders, no refills, no chemicals building up in her system.

Hear it from our customers

I'd been doing the monthly Bravecto thing for years. Every dose, my cat Milo would hide under the bed for two days, scratch at his neck like crazy, and act off. I finally couldn't keep doing it to him. Tried Catwise as a last resort — clipped it on, didn't think much of it. We're 4 months in. No fleas. No ticks. And the best part: Milo doesn't even know it's there. He sleeps next to me again.

I always told myself indoor cats don't need flea protection. Then I brought a few houseplants in from the garden last summer and within a week my Luna was crawling with them. Pure nightmare. Got Catwise the same day I found out, clipped it on her once we'd treated the infestation. Six months later, completely clear. I now keep one on her year-round — peace of mind I didn't know I was missing.

We have 3 cats and an acre of woods behind the house. Last May my oldest, Biscuit, came inside with two ticks behind his ear. That was the moment for me. Found Catwise, bought the 4-pack, put one on each cat. It's been almost a year now and not a single tick on any of them. One purchase, one year, three protected cats.

My senior cat Poppy has had skin reactions to every flea collar we ever tried — red, raw neck, constant licking. Our vet specifically warned us off the "natural" ones because of the essential oil issue. I asked her about Catwise before ordering, she looked at the ingredient list and said it looked clean. We're 5 months in: no irritation, no licking, no fleas. At her last check-up, our vet said Poppy's coat looked the best it had in years.

What's Inside

🌲 Atlas Cedarwood Oil From the Atlas cedar (Cedrus atlantica). Its active compound, cedrol, has been used for decades as a natural insect repellent. Unlike Eastern Red Cedar, it's free of the phenols that harm cats.

 

🌹 Geraniol A plant-derived compound recognized by the U.S. EPA as a safe, effective insect repellent. Found naturally in roses and geraniums. Disrupts fleas' and ticks' ability to detect your cat.

 

🍋 Lemongrass Extract Used at feline-safe concentrations to extend the protective zone around your cat. Works synergistically with geraniol for longer-lasting protection.

 

🌿 Soapwort Extract (Saponaria officinalis) A naturally occurring source of saponins that gently disrupt the protective coating of flea eggs and larvae on contact. A traditional ingredient in cat-safe pet care.

 

🌱 Rosemary Hydrosol The water-based distillate of rosemary — far milder than the essential oil and safe for cats. Acts as a natural deterrent against mosquitoes and biting insects.
