Sound familiar?
You buy a harness, put it on, and your cat freezes, flops over or wriggles straight out of it. So it goes in a drawer, and your cat goes back to watching the world through the window.
Usually it's not your cat. It's a harness that doesn't fit right and no plan for introducing it.
Exploring hikes and parks with you
Soaking up the sun on the balcony
Sniffing the grass in the backyard
Not every cat wants to walk, and that's fine. The goal is a cat who's happy and safe outside.
How the challenge works
Each morning, a short email tells you exactly what to do that day. Keep sessions short, 2 to 3 times a day, and always reward with treats.
Let your cat sniff the harness, with treats, then drape it over their back for a few seconds.
Put it on for 2 to 3 minutes at a time, during a meal or play.
5 minutes per session. Give them a treat whenever they walk in it.
10 minutes per session. Encourage them to walk around, and reward them when they do.
10 to 15 minutes indoors. Follow your cat with the leash loose, rewarding them as you go.
10 to 15 minutes sitting together at the door or on the balcony, with treats.
5 to 10 minutes in a quiet spot. Reward them with treats while you're out.
Only move to the next step when your cat is relaxed: eating, playing and moving normally in the harness. If they freeze, flop or try to back out, go back a step and repeat it for as long as they need. Many cats need more than 7 days, and your 30 days covers that.
Why the challenge works
Guessing the fit and hoping for the best
Losing motivation and deciding your cat just doesn't like going outside
Putting the harness on and heading straight out
No idea what to do when your cat freezes
Not knowing when to pause or when to move on to the next step
Stuck with it if it doesn't work out
A fit guide to get it right from the start
A morning email to keep you going, one small win at a time
Short daily sessions, from indoors to outside
Know exactly what to do if your cat isn't ready yet
Clear signs for when to pause and when to move on
30 days to get there, or your money back

The harness
Escape-resistant where it matters, minimal everywhere else, so your cat stays safe and still moves like a cat.
Gently tightens if your cat tries to back out, helping keep them secure.
Less bulk, so your cat can move naturally.
Canvas, mesh and neoprene for comfort outdoors.
Strong, reliable buckles you can trust.
Available in black and taupe.
Why I started CATFIT
When I wanted to take my cat Luka outside, I couldn't find a harness that was escape-resistant and minimal. We tried H-style, vest and jacket harnesses before finding a martingale-style design that actually worked for him.
CATFIT is the harness I wish I'd found first, and the Happy Outside Challenge is the plan I wish I'd had.

Every cat learns at their own pace. That's why you have 30 days.
If you've followed the plan and your cat still isn't comfortable outside in their harness within 30 days, I'll give you your money back.
