After birth, Garfield cats will slowly increase their IQ as they grow, and will eventually be around 2 to 3 years old. Whether it is a cat brain or a human brain, its structure is generally the same. The only difference is that the neocortex of the human brain is more developed, which is incomparable to the cat brain.

Methods to test a cat’s IQ

1. Test the way you hold the cat. Hold the cat's armpits with both hands. If the cat breaks free, it is a smart cat. If the cat doesn't make any resistance, it is a stupid cat.

2. Put the sock on the cat’s head. If a cat quickly takes off its socks with its paws, it is a smart cat. If you panic and run away after being put on socks, you are a stupid cat.

2. Wall-bumping test. First pick up the cat and then pretend to touch the wall with its head. If a cat puts its hand against the wall, it is a smart cat. If it cannot block it with its hand and is waiting to be hit on the head, it is a stupid cat.

3. Plastic wrap barrier test. Place plastic wrap at the door. If the cat can see the obstacle, it is a smart cat.

4. Snack test method. Place the snacks at the bottom of the bowl, then add a full bowl of water and put the cat's favorite snacks at the bottom of the bowl. If a cat can use its claws or other methods to take out snacks, it is a smart cat. If you drink water directly, you will be a stupid cat.
