Before the first drop
The questions that arrive before the first pipette is ever opened — answered from the label, in the order they usually come.
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.
Almost certainly not — the adults you can see are about five percent of an infestation. The eggs and larvae already in the home keep hatching for a while, and a heavy infestation takes three to four months of steady monthly doses to fully clear.
The formula is fragrance-free, quick-drying and non-greasy. Most cats forget the application before the applicator is back in the box.
One product fits all of them; each cat simply needs its own monthly dose. Count the cats, multiply by months, and pick the box that covers the total.
Because the pests come in — on people, dogs, bags and boxes. The guide How fleas get past a closed door lays out the whole route map.
