Mum warned me it's hard to spray medicine on my cat as he's afraid of the sound of that, even though the medicine doesn't hurt. I believed her and began thinking of what I'll do if I fail with this task. But when the time came, I just grabbed the disappointed sleepy cat, half undressed him (he wears a shirt these days ^^), and sprayed the medicine under the paw. Some also got into my nose - but that doesn't matter. The cat seemed not to have understood what had happened, and only danced a little when I was putting the shirt back on him.
I've noticed this a long time ago - that he goes crazy when mum tries to use medicine on him, and when I do it, he is rather calm. ^^
