It can be difficult to give a cat a pill, and some cats get so upset by the pilling process that they start avoiding their pet parents altogether. For this reason, scientists have searched for alternative ways to give cats medicine. One approach tried with medications sometimes used to treat fear and anxiety problems (TCAs and SSRIs) was to give the drug transdermally (though the skin). This was usually done by putting medicine on cats’ ears. However, researchers discovered that only 10% of the medicine was actually absorbed. (Because of this, SSRIs should not be given through the skin.)
A better approach for getting your cat to take her medicine is to find a pharmacist who will compound the medicine for you. After making it into a powder or a liquid, you can put the medicine into a strong-tasting and strong-smelling liquid that your cat likes, like tuna oil. If you give your cat a bit of tuna in oil for a few days in a row, you can then add the medicine to the tuna oil. If your cat won’t eat the mixture, use less medicine at first and gradually add more as your cat accepts it.
