On a similar note, THE most common search term on the GardenBanter
website is for Coleus canina, a plant that is supposed to deter dogs &
cats because of the smell.

The people at bionet.plants are however, less than impressed with it's
qualities.

I agree. I was suckered into buying these "pee-off" plants. The
neighbourhood cats took delight in doing their nasty business directly on
top of the plants!
