Catnip does expire. Cat mint powder products purchased in the market by cat owners have a shelf life. For the specific shelf life, please pay attention to the product instructions. Expired catnip powder products will lose the efficacy of the product, so it is recommended that cat owners pay attention to the shelf life of the product when purchasing and do not buy expired products. If the catnip powder that has been idle at home for a long time has exceeded the shelf life, it is best not to use it on cats.

Methods to avoid using expired catnip on cats:

1. Owners can grow catnip themselves, which can grow for many years and keep cats fresh for a long time. Mint leaves.

2. Catnip leaves can be dried, crushed and stored in a sealed bag.

3. When purchasing catnip powder, owners should pay attention to the shelf life and do not buy products that are about to expire or have expired.

4. The owner only needs to purchase an appropriate amount of the product. Do not buy too much and end up leaving it unused and expired.
