There are some cats that react negatively to Advantage drops.
Here is a discussion board where this is discussed by owners http://pub123.ezboard.com/fsunshine35446frm9.showMessage?topicID=905.topic
One of the things they note on the board is that there are drops out there that are *fake* ones that show the animal's weight measured in KG not pounds.
For information from the company you can try calling Bayer Veterinary Services at 800-422-9874 for information on adverse reactions to their Advantage drops product.
Hope this helps your cat!
