Catnip can be placed directly on the cat scratching board. Most cat scratching boards are made of corrugated paper. Both powdered catnip powder and catnip leaves can be placed directly on them, but be careful to keep the cat scratching board clean. It is recommended that cat owners feed their cats appropriately. Generally speaking, it is recommended that cat owners feed their cats the amount of a fingernail at a time, and no more than once a week.

Precautions for feeding catnip to cats:

1. Do not feed milk cats. Cats should be fed after they are 8 months old.

2. Pay attention to the appropriate amount of feeding and do not overfeed.

3. If there are multiple cats at home, it is best to isolate them when feeding to prevent them from getting excited and fighting after feeding.

4. Do not give catnip to pregnant cats to prevent the cat from being too excited and running and jumping, leading to miscarriage.
