I don't know what to tell you except some orchids STINK! I have one which reminds me of a public restroom in a NY subway. Some smell like punky feet, mothballs, rotting meat...

If the flowers are beautiful, I put up with the smell or put the plant in another room. Some only smell at night. Those get locked up in a closet or put outside over night.

Huh. I have never smelled a Cattleya that smelled like urine. I would not like that at all. I am quite sensitive to smells- I had to give away my Oncidium ornithorhynchum because of the smell. My Cats smell like all kinds of things; citrusy, rose-like, sweet, powdery, I like the sweet/hinkey smell of the walkerianas and their crosses- but sometimes the hinkeyness is a bit much. What is this cattleya's name? And are you sure that maybe a kitty-cat didn't just spray it? They do that sometimes.

I have a very large collection of "cattleyas" and have never had any that smelt like Urine.
I prefer to say that Oncidium ornithorhynchum has a strong perfume rather than a smell.

It you want a smelly orchid try Liparis reflexa. It smells like roaming undesexed Tom Cat Widdle. Yuk!

Depends a lot on the pollinator that visits the wild ancestors.

My favourite orchid Perfume is produced by B. nodosa at night. When you open the glass-house door in the morning, it is a delight.
