The nape gets the drop
Sixty seconds, one pipette, on the skin where grooming can't reach. The rounded tip goes straight to the point.
One drop. Thirty days. Repeat.
The first of the month belongs to Catego.
Every cat runs on rituals — the dawn patrol, the noon nap, the supper stare. Catego adds one more: a single spot-on drop at the nape, once a month, and fleas, ticks and chewing lice spend the next thirty days locked out of all the others.

A month of protection in four beats
Six hours later, quiet
Fleas die on contact — no bite required — starting within six hours of the drop landing.
Thirty days of hold
One dose keeps fleas, flea eggs, larvae, ticks and chewing lice off the roster until the next first of the month.
The cycle stays broken
Eggs and larvae never graduate. Re-infestation is cancelled before it's scheduled.
Know the pests on the label
Four names, one drop. Everything Catego bars from the coat, and why each one earns its place on the list.
Adult fleas start dying within six hours of contact with a treated coat — no bite required. A single female lays up to fifty eggs a day, which is why speed matters more than it sounds.
Do the flea math →Pyriproxyfen, the growth regulator in every dose, stops eggs and larvae from ever maturing. The colony ages out instead of replacing itself — that is what actually ends an infestation.
See the pyramid →Ticks must bite to live and reproduce, and the bite is how Lyme disease and cytauxzoonosis travel. Catego kills ticks through contact, before the bite happens — indoors and out.
The tick briefing →The often-forgotten third pest on the label. Chewing lice spread cat to cat in multi-pet homes; the same monthly drop that guards the coat against fleas bars them too.
One box, every cat →Contact kill, not bite-and-hope
Most oral flea medications work only after the pest bites your cat. Catego works the other way around — contact with the treated coat is enough, so the bite that spreads disease never has to happen.

Field notes between doses
The knockdown starts within six hours of application, and the flea life cycle breaks with it.
Fleas, flea eggs, larvae, ticks, chewing lice — one dose bars the entire list for thirty days.
A single formulation fits every cat over 1.5 pounds — the whole household shares one supply.
Adults you can see are 5% of the colony. The other 95% — eggs, larvae, pupae — is what the monthly cadence starves out.
Households on the cadence
Multi-Month
Applied the first dose on a Sunday; by Monday breakfast the scratching had stopped. Three months later the spring box is a household institution.
Full-Year Box
We keep the year box next to the coffee tin. First of the month, coffee gets brewed, cat gets dropped, everyone moves on with their lives.
Starter Dose
Bought a single dose to test on our very opinionated tabby. No smell, dry by evening, and she never clocked the application. Upgrading to the six pack.

Asked before the first drop
Adult fleas, flea eggs, flea larvae, ticks and chewing lice — all from a single application, for thirty days.
Within six hours of the drop touching the coat, fleas begin dying. No bite is required at any point — contact is enough.
Cats and kittens over 1.5 pounds and at least 8 weeks old, indoor or outdoor, any breed or coat. It's one formulation for all of them.
No prescription is needed to buy Catego. That said, for pregnant, elderly, medicated or unusually small cats, a quick word with your veterinarian is always the right first drop.
The Catego handbook: everything the box knows
The short version of Catego fits in a sentence — one spot-on drop a month keeps fleas, ticks and chewing lice off a cat. The long version lives on the label, and this handbook unpacks it: what's inside the pipette, how the chemistry works, how to apply it safely, and how to pick the right number of doses for your household.
01What's inside a Catego dose
Each pipette carries three active ingredients that divide the work. Dinotefuran (22.00%) is the fast punch — it starts killing adult fleas on contact within six hours. Fipronil (8.92%) sustains the attack across the month and extends it to ticks and chewing lice. Pyriproxyfen (3.00%) is an insect growth regulator: it doesn't chase adults at all, it stops flea eggs and larvae from ever maturing, which is what actually breaks the infestation cycle.
The trio is why one dose covers every stage of the problem at once — the fleas on the cat today, the ticks on tomorrow's patrol, and the eggs already hidden in the carpet.
02Who the label covers — and who it doesn't
Catego is formulated for cats and kittens over 1.5 pounds and at least 8 weeks of age, indoor or outdoor, in a single one-size formulation — there are no weight bands to match, which is what makes one box workable for a multi-cat household.
- For external use on cats only — never on rabbits, dogs or other pets
- Not for debilitated, aged, medicated, pregnant or nursing cats without a veterinarian's sign-off
- One tube per cat per month — never more than one tube per treatment
- Keep the box away from food and out of reach of children and paws
- Watch the application site afterwards; slight, brief redness or scratching can occur — persistent signs are a call to your veterinarian
03Choosing a supply size
Every box holds identical doses; the counts just map to different calendars. As a rule the per-dose price improves with the bigger boxes, but the retailer sets prices and they drift — check the math at checkout.
| Box | Doses | Covers | Fits best |
|---|---|---|---|
| Single Dose | 1 | One month | A first meeting, a foster, a trial run |
| 3-Month Pack | 3 | A flea season | First open window to first frost |
| 6-Month Pack | 6 | The warm half of the year | Long summers, one winter reorder |
| 12-Month Box | 12 | A full year | Standing-order households, zero reorders |
04Why contact kill matters
Fleas and ticks are dangerous mostly through their bite: that's how flea allergy dermatitis starts, how anemia develops in small cats, and how pathogens like bartonellosis, Lyme disease and cytauxzoonosis travel. Oral flea medications only work after the pest has bitten. Catego's actives kill through contact with the treated coat — the pest dies before the delivery mechanism fires, which is the whole point of prevention.
05The cadence, honestly
A dose protects for one month, and the calendar is the whole trick. If the home already has an infestation, expect three to four months of unbroken monthly doses before every hidden egg, larva and pupa has cycled out — the visible adults are only about five percent of the colony. Pair the doses with laundering what can be laundered and vacuuming the favorite napping routes, and the pyramid comes down for good.
The next first of the month is coming.
