Everything to open up the outdoors to them, at their own pace.
The vest harness that opens up the outdoors to an indoor cat, and the lead that follows their curiosity. Adjustable, lightweight, designed for the chest — never the neck.
All three of our harnesses are vest harnesses: they spread the pressure across the chest instead of pulling on a thin strap. For a first outing, the vest harness kit, from S to XL, comes with its lead. If your cat refuses thin straps or is a large cat, the velvet comfort vest goes up to 3XL. For a kitten or a small cat, the reflective harness comes in XS and S, lead included. The criteria are in our guide to choosing a harness.
It greatly reduces the risk without removing it: no harness is foolproof. A cat that escapes almost always backs out head down, and a vest harness leaves them less room to manoeuvre than an H-style harness. The rest comes down to the fit, checked before every outing (two fingers flat under each strap, no more), to gradual harness training at home and to your vigilance: lead in hand, never pulling on it. If they've already managed to slip out, here's what to do when a cat escapes their harness.
Take two measurements with a soft tape measure, close to the body without compressing the fur: the chest girth, just behind the front legs at the widest point (the measurement that matters most), then the neck girth, where a collar would sit. Compare them with the size guide on the product page: weight and age aren't enough. If your cat is between two sizes, take the larger one. The step-by-step is in our guide to measuring your cat.
From 8 weeks (2 months) to get them used to it, indoors and never before weaning, in sessions of a few minutes, supervised. For outings, wait until their primary vaccination course is complete and your vet gives the go-ahead, at around 16 weeks (about 4 months). Choose the size by measuring them, not by their age, and recheck the fit every two to three weeks. For a small cat, the reflective harness comes in XS and S. The details: kitten harness, what age to start.
For the first outings, a fixed, light, short lead, 1.5 to 2 m long, keeps your cat within reach: the one in the vest harness kit is this type. The retractable lead takes over once they walk confidently in a harness: 3 m to keep them close, 5 m for more open spaces, with a brake under your thumb that stops the lead paying out. Either way, it clips onto the harness ring, never onto a collar. The comparison: which lead to use with a harness.
They don't do the same job. A collar is for identifying your cat day to day: choose one with a safety buckle, like our breakaway collar, which comes apart when pulled if it gets caught on something. A harness is for outings: it spreads the pressure across the chest rather than the neck and, well fitted, it is much harder to slip out of. So a lead is never attached to a collar. The full comparison: harness or collar.
