I have wrestled cats to apply flea treatment and eye ointment. I have prised open the biting jaws of vicious felines to drop down worming tablets. I have chased after chickens and manically thrown myself at them to grab them and check their health and vitality (not their stress levels). I have even given medicine to a box full of tens of thousands of stinging bees. All this and I have only just learned that these things are nothing compared to trying to give eye drops to a nine month old little man.
