1. Cat suffocation and insufficient blood supply. Grabbing a cat's neck can calm it down temporarily, but if done for too long, it can cause the cat to suffocate. This is common in adult cats and can lead to insufficient blood supply to the brain.
2. Becomes sensitive. When you choke a cat, it will feel very uncomfortable for a heavier cat, and it may even make the cat very sensitive.
3. In severe cases, it can lead to the cat's death. In serious situations, strangling the cat can cause death, and if the cat reacts strongly, it may even scratch its owner. 
Will choking a cat cause it to hold a grudge against its owner?
Grabbing a cat by the neck might cause it to hold a grudge against its owner. Every cat has a different personality, so owners can try feeding it small treats or canned cat food to appease it. Cats have short memories and may forget things after a while, but choking a cat will make it uncomfortable and frightened. If you frequently choke a cat by the neck, it may become less affectionate towards its owner. When raising a cat, avoid excessive scolding or hitting. When you discover your cat has misbehaved, you need to calmly and patiently discipline it.
