George shows us how to remove pollen from lilies, before the anther opens

Removing anthers ruins the beauty of the lily flower. Unfortunately very common procedure still.

My dad : hoover them

I received a beautiful bouquet of Stargazer Lilly's from someone only to find out two day's later the flower..the leaves and their pollen are highly toxic to cat's and can cause renal failure. I immediately put them out on my terrace and tried to thoroughly decontaminate my apt. But now I don't know how to dispose of them once they die as they are still living fine in a vase of water on my terrace with flower food added. I'm wondering once the flower's die is that pollen on them still poisonous ? Any info you can offer is appreciated. My kitty is fine so far..I removed the flower's to the terrace Monday evening and it's Thursday now...she has no symptoms. I'd kept them high up where she couldn't get to when they were inside as I do with any flower's but in a window sill and pollen may have fallen ..which I've vacuumed thoroughly now and wiped all furniture down with damp cloth. They are so beautiful but florist rarely put warning labels on them for cat owner's.
