It's not funny

Poor old Toots. She has cataracts and managed to scratch her eye. To treat the ulceration is a bit of a problem, the first cream did not work, hopefully this will help.

It was instructive to overhear the vet advising an elderly deaf customer how to treat his dog and house for flea infestation. Everybody in the waiting room reflexively started scratching non-existent itches.

You want to scratch now or have already done so! See if you can resist an impulse that is as old as the hills. :-)))
