My 3-legged house cat, Lucky, managed to get up on the kitchen table to smell a bouquet of lilies our neighbor brought to us.

He could not hide the evidence.

He is missing a back leg, and normally cannot manage to jump up on the kitchen chair to make it up on the table - but I guess the desire to smell the lilies gave him an extra boost. I never dreamed he would be able to make it or I would not have left them on the table.

We carefully wiped off all we could, but being so close to his eyes, we didn't want to use anything to strong. That yellow stain was there until fall, when he shed his summer coat for his winter one.

Ah, how sweet! Now we know how to remove pollen stains from curious kitties' noggins.

Not sure where I heard of this, but have used this method for the last 30 years.
When lily pollen ends up on your blouse or shirt, walk gently to the house, turn on your vacuum cleaner, and hold the round tube part (without any accessory) directly over the pollen. It sucks the pollen directly off of your clothing fibres. DO NOT TOUCH OR BLOW OR RUB AT IT, BEFOREHAND. This would rub it into your cloth fibres, and result in a stain.
Vacuuming it off cleanly, is the best technique I've found.

For depollenizing Lilies in a bouquet, I take a soft tissue, envelope all the pollen anthers from the center of one Lily blossom and pull. They usually all come off together. Carefully discard tissue, which is now contaminated, and use a fresh tissue for the next bloom. And don't do this over a tablecloth - accidents can happen!

As for taking it off of a pussycat - approaching with a vacuum tube might result in scratches and blood. Maybe a tissue is best in this case.

An even better way to deal with lily bouquets is to remove the anthers with your fingers (or tweezers) before the anthers open and release the pollen. This point in time is when the bloom is just opening.

Of course if the pollen has already released, then stick to the tissue method!
