Most products attack the flea's nervous system. The same chemicals attack your cat's.
The active ingredients in most flea products are neurotoxins. They're designed to release into her fur, attack the flea's nervous system, and shut it down. But the same chemicals don't stop there. When she grooms herself, she swallows them. When they sit on her skin, her body absorbs them. Once inside, those same neurotoxins start working on her nervous system too. That's why the FDA has logged over 88,000 reports of seizures, tremors, and loss of muscle coordination in cats since 2018.
"Built by a cat owner who refused to choose between fleas and chemicals." — Feline Wellness Monthly
Sarah's cat had a seizure two days after a routine flea treatment. The vet said it was a known reaction to the active ingredient — and that there wasn't a safer alternative on the market. So she built her own. Not to start a company — to protect her cat. When her cat stopped scratching and started purring on her chest again, she started making pendants for friends with cats. Today, over 10,000 cat owners use her formula.
No pills. No drops. No ongoing chemicals.
This simple
1. Clip it on her collar
2. Our SmartRelease technology releases a plant-based blend around her. (You won't smell it)
3. Fleas and ticks can't stand it, so they don't land, don't feed, don't nest.
4. Finally, she's protected for 12 months.

Frequently Asked Questions
How is this different from normal flea & tick treatments?
Most best‑selling treatments (and even “natural” options) either put chemicals on your cat’s skin or into her blood, or they’re dog formulas resized and relabeled. Catwise is a pendant that uses a cat‑specific blend of ingredients in micro‑dose around her, so fleas and ticks can’t stay, feed, or hatch on her without anything entering her body.
How is this different from “natural” flea collars on Amazon?
Most “natural” flea collars for cats are just dog products rebranded. They often use essential oils and plant extracts that a dog’s liver can handle but a cat’s can’t, which is where liver stress and reactions come from. Catwise was formulated for cats first, with doses and ingredients chosen around feline biology instead of shrunk‑down dog math.
How quickly will I notice a difference?
Most cat owners see less scratching and fewer live fleas in the first 7–14 days. Between 2–4 weeks, fleas and ticks on the cat and in her usual sleeping spots are usually gone, as existing parasites die off and no new ones stay to bite or lay eggs.
Does it also help if my cat already has fleas or ticks?
Yes. Catwise doesn’t only prevent new bites. The same protective “halo” that keeps new fleas and ticks from staying also makes it impossible for existing ones to live on her, so the infestation on your cat dies out instead of restarting.
Will my cat smell or feel it?
In normal use, no. Catwise runs at a dose so low that you and your cat shouldn’t notice a smell or feel a change in behavior. For fleas and ticks the blend is unbearable; for your cat it’s designed to be invisible in daily life.
Is it safe if my cat grooms herself a lot?
Yes. Catwise was built assuming your cat will groom frequently. The formula and dosing are chosen around feline metabolism, not dogs, so it avoids the common problem of dog‑style “natural” formulas that rely on oils cats can’t process well.
Does my indoor‑only cat really need this?
Fleas and ticks don’t care if your cat goes outside. They ride in on shoes, clothes, bags, and visiting pets, then choose the warmest body in the home. That’s why so many “indoor‑only” cats still end up with fleas. Catwise gives constant protection without changing her routine.
