The reasons why adult cats do not eat or drink for 5 days after arriving in a new home:

1. Cats will be very nervous when they arrive in a new and unfamiliar environment. The stress will increase, and the cat’s appetite will decrease. If it drops seriously, you may not be able to eat.

2. Cats are not familiar with their new owners and are wary of people and things around them. They will also become anxious and hide in corners without eating or drinking.

3. If the cat eats food that is not the cat food it likes to eat before, it will cause the cat not to eat or drink. If you need to change the cat food, you should do it step by step. You can mix the two kinds at first and then change slowly. .

4. It may be because they are too attached to home. Because adult cats are different from kittens, they are more sensitive to changes in the environment, so they are more likely to feel anxious after arriving in a new home.

What to do if an adult cat arrives at a new home without eating or drinking for 5 days:

1. Let the cat slowly adapt to the new environment.
2. Prepare easily digestible food for the cat.
3. Supplement the cat with certain digestive enzymes.
4. Change the cat food that your cat likes to eat.
5. The new owner should communicate more with the cat and stroke the cat’s head so that the cat can trust the new owner.
