Catnip cannot transform hair. Catnip is a Chinese herbal medicine. Feeding cats mainly excites cats. It also promotes intestinal peristalsis and helps cats induce vomiting. Cats have the habit of licking their hair and will eat the hair into their stomachs. It is recommended that cats be fed special cat grass. It is best not to use catnip to prevent cats from eating too much catnip and causing over-excitement.

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.
