Several years ago I bought a pot of fresh basil and had it sitting on the kitchen windowsill, handy to pluck a leaf or two. After a couple of days Himself and I both noticed a very objectionable smell, as though a cat had sprayed around the kitchen - and we realised it was the pot of basil. From that day on, fresh basil has never seen the inside of my kitchen.

I don't enjoy the smell of cat wee in my food.
