Because difficulties are often encountered with chronic oral drug administration in cats, topical formulations of many drugs are being offered to cat owners. While this route of administration is convenient for owners, there are currently only a handful of drugs that have been specifically formulated and tested for topical administration. Determining which drugs can successfully be administered topically requires pharmacokinetic studies (measurement of the time course of drug concentration in the blood). This pharmacokinetic study will determine if three drugs used for treating behavioral diseases in cats can be administered topically safely and effectively.
