Cinnamon or Cayenne pepper spray??

[Liz0]

First, Hi everyone I'm Liz

So today my mother in law and I where visiting the local nursery and they had these gorgeous and funky Dendrobium type orchids that I personally had never seen before.

I bought two thinking they'd look great in our southern window (and they totally do!) however i didn't consider my cat. She wants to chew the leaves so bad. I've been reading a lot and most sites are recommending Cinnamon or a Cayenne pepper spray on the leaves.

I've read cinnamon has been used to help heal some orchids from fungus? But how would it be permanently on the leaves? or at least a month or two till the cat loses interest? Same with the cayenne pepper? I know cinnamon probably will be the first recommendation but I'm worried if that doesn't work then how about the cayenne pepper? and I'm talking directly on the leaves not in the soil.
Thanks!
