The best escape proof cat harness is not only secure, it’s comfortable for the cat. These are the two I like best. When fitted and used properly, they’re virtually escape proof. And they’re so light and comfortable, the cat barely knows the harness is there.
Lupine H-Style Cat Harness
H-style harnesses work best for cats because they buckle around the cat’s neck and middle, rather than slipping over his head. Although there are many H-style harnesses in pretty patterns and colors these days, my favorite escape proof cat harness is the one made by Lupine

How To Keep Kitty From Getting Out Of Her Harness
Taking a cat outside on a harness and leash may sound scary at first. But if the harness is fitted correctly and you remember a few simple tips, you’ll never have to worry about kitty escaping and venturing off on her own.
Measure First: Put a tape measure around your cat’s neck, making it tight enough that no fingers fit between her fur and the tape measure. With the cat standing up, also measure her girth right behind the front legs. Add about five percent to each measurement.
Check the measurements of the harness before you buy to make sure it’s the right size. If it’s too small, the cat will be uncomfortable. If it’s too large, she’ll be able to squirm out of it.
The ‘Purrfect’ Fit: If you can slide just one finger between the harness and the cat, it’s just right.
Check The Buckles: Most cat harnesses have plastic buckles that snap together. Make sure to snap the buckles correctly. If just one prong is sticking out or missing, the buckle will come apart.
Hold the leash behind the cat and keep it slack. Backing out of a harness is almost impossible if the leash is behind the cat. If the leash is too taut, the harness can pull open if the cat lunges or starts to run. Remember, the buckles are designed to open under pressure.
Never tug on the leash. This, too could cause enough pressure for the buckles to come undone. If your cat goes under the deck or car, be patient and wait for her to come out, or try to gently push her out with your hands. You might be able to lure her out with treats, too. I always have a bag of treats in my pocket when I’m outside with a cat in a harness and leash.
Don’t panic if your cat gets out of the harness. She’ll probably be so surprised she’ll just sit down. Sit on the ground and encourage her to come to you. When she does, reach out slowly and pet her. When she’s very close to you, calmly pick her up.
If she starts to wander off, don’t run after her. A cat can outrun a human any day, and the sound of you running behind her will make her go faster. Walk calmly and slowly. Say her name in a friendly voice. When she stops, bend over or sit on the ground and encourage her to come to you.
Always supervise your cat when she’s outside on a tie-out. She could be injured by an animal or human passing through your yard, and the tie-out can get tangled in bushes or wrapped around trees.

How To Walk Your Cat With a harness and leash.
With most any harnesses a cat can put its front legs together, narrow it’s shoulders and slip out of it backwards. All you can do about it is keep the leash line angled as straight up as possible and tension on the band behind the front legs when an escape is likely. A harness that will cinch up a bit tighter behind the front legs helps too. Until someone puts a tail loop on the harness to prevent backing out of it, they can escape.
If you venture out in public where you may encounter dogs off leash things can get bad quickly. You should be able to lift your cat up with the harness to help it out of harms way. You are likely to get scratched and bitten in any case. An electric stun cane is effective to deter dogs if they get in close, I’ve done this. Otherwise a Mace pistol will stop them at long range but is hard on them as would be on you, not done this yet but carry it in case of attack.
Second not all but some cats that do get out are not surprised and do run immediately no matter if you give them all the cat nip and treats in the world.
