Overwhelming suggestions given as to how to clean Hat's ear, without my hands being shredded:

1) Sister J suggested tying him up, 2 paws together, like a wild boar. Cats are great escape artist, so I think Hat will slinker his way out very quickly.

2) Vegie suggested blindfolding, or use catnip to make Hat groggy. Hat doesn't respond to catnop actually. And I couldn't find a cat-sized blindfold.

3) Sister S tried wrapping Hat in a sarong, the knot tied at the back of his neck, and his paws enclosed. With disastrous result.

4) My staff suggested knocking Hat unconscious, then tie his 4 paws to the bedposts. Too violent.

5) Colleague suggested drugging Hat with alcohol or cough syrups. I don't know if this is safe. Anyway, she tried it on her dog, it didn't work. The dog became more excited after vodka/ glucose mixture.

6) Sister S had another idea. Enclose Hat in a bolster case, and tie the drawstring at his neck, so his paws are enclosed, like a sausage. I had already bought a kid bolster case, on stand by.

7) Jennifer suggested wrapping Hat in a towel mummy style, one person holding him, while the other giving the eardrop. It is similar to the sarong method.

Each suggestion has its merits. I just have to find a best way.
