What age should you stop picking up cats by their neck?

You should never pick up a cat by the scruff of its neck, regardless of its age.

Here's why:

* It's painful and stressful for the cat: The scruff is a sensitive area, and grabbing it can cause pain and discomfort.

* It can damage the cat's neck: Rough handling can cause injuries to the neck, especially in kittens.

* It's not a natural way to handle cats: Cats instinctively scruff each other when they are kittens, but this is a temporary behavior that disappears as they get older.

* It can lead to behavioral problems: Cats who are routinely picked up by the scruff may become fearful or aggressive.

Instead of picking up a cat by the scruff, use the following methods:

* Support the cat's chest and bottom: Gently scoop your hand under the cat's chest and support its rear end with your other hand.

* Use a cat carrier: If you need to transport your cat, use a carrier that is the right size and is properly secured.

Remember, always treat your cat with respect and care.
