These reviews can serve as a guide to get you started in finding the perfect harness for your kitty. It’s particularly important to note that no harness is 100% escape-proof! They must be fitted and used properly for maximum escape-proofability.

Buyer’s Guide: Choosing the Best Escape Proof Cat Harnesses
How Can I Make Sure My Cat Doesn’t Escape Its Harness?
No harness is 100% escape-proof, no matter what a manufacturer or seller may tell you. Choosing a harness that is designed to be escape-proof is a good start, but you must ensure the harness fits your cat correctly. It should be snug without squeezing. Some people underestimate the size of their cats or inappropriately measure them because of the thickness of their fur. Your cat’s harness should fit their body, not their fluff.
If you use a harness that is too small or too large for your cat, you are risking an escape. Cats can be escape artists, especially when frightened. Make sure you acclimate your cat to the harness safely in your home for at least a couple of weeks before attempting to introduce them to the outdoors. Ways to help prepare your cat for the outdoors can include allowing them to sit in screened, open windows so they get used to the smells and sounds and taking your cat out in a secure carrier for short periods of time.
What to Consider when Choosing the Right Escape Proof Harness for Your Cat
- Size: How to fit your cat for a harness involves using a soft measuring tape to measure the neck and chest. These measurements will help you choose a properly fitting harness. If you need help, get a second set of hands so you can feel confident in your measurements. If you get improper measurements and purchase a harness off on those measurements, you may end up with a harness that allows your cat to escape.
- Age: If your cat is a kitten and still has a lot of growing to do, consider choosing a less expensive harness for training purposes, but invest in a higher-quality harness when they are older. Kittens are still learning about the world and should not be taken on adventures until they are fully vaccinated, so this gives you time to help them get used to the feel of a harness without leaving your house.
- Coat: As previously mentioned, you must measure your cat based on their body measurements, not their fluff measurements. Some cats have very thick coats that may cause you to get larger measurements than their true size. A too-big harness can allow your cat to back out of the harness or jump forward out of it.
- Usage: Where you intend to take your cat can guide you in choosing the right harness. If you intend to take your cat into a fenced yard, then you have some space to choose a harness that may not be the most secure harness on the market. However, if you’re taking your cat hiking or walking near busy roads, then you want to choose an extremely secure harness, even if it means spending more money to get it.
