Vaccines purchased online or injected at a pet hospital will have a batch number on the bottle (regular hospitals will issue vaccination certificates to cats, and the vaccines the cat received will be posted on the certificate). Then log in to the China Veterinary Drug Information Network to query. ​​​​​​

There are several ways to identify:

1. Check whether the handwriting is clear (there are Chinese markings on the powder bottles since 2008.08)

2. Check whether there is a veterinary drug animal inspection label (since August 2005, all products have an anti-counterfeiting label on the bottle cap)

3. Check whether the powder bottle is vacuum (regular ones are all vacuum, non-vacuum ones are either invalid or fake)

　4. Check whether there are cracks in the powder (there are cracks in the failed seedlings)

5. Look at the color and dissolution speed of the fusion (very easy to dissolve, light red color without precipitation)

6. The bottle label is not easy to tear off (but it will fall off when it is touched by alcohol)
