You CAN get a cat used to taking meds. Smokey the YOunger had an eye infection that wasn't responding so I had to give her 4 different antibiotic creams over a 3 month period. At first it was a 15-30 minute ordeal twice a day of "where's Smokey?" Gradually, she realized that she WAS going to get her eye meds and finally made only the token fuss required by the Cat Union.

Good luck!
