**Why Do Cats Fall Over in a Harness?**
When a cat wears a harness, it can trigger a survival response similar to being grabbed by a predator. This is because the harness puts pressure on the same areas that a predator would grab, such as the shoulder blades and chest. As a result, the cat may fall over and freeze in order to protect itself.
To help your cat get used to wearing a harness, start by slowly introducing it to the harness. Let them sniff it and get used to the feel of it before putting it on them. Once they are comfortable with the harness, start practicing walking them on a leash in a safe, indoor area. With patience and training, your cat can learn to overcome their fear of the harness and enjoy going on walks with you.
