moss PEE SMELL

[missann]

I am really new to the use of moss and I have noticed a strange pee like smell in the moss that I have wrapped around my vanda's roots. I thought it was because it was hanging directly over my bunny cage. I moved it away, and then today I recieved a moss basket liner in the mail and it, too smells like pee. This pee smell from the moss is permeating my entire house, and the deck, and my bedroom. I am curious to know if the smell is actually caused by ammonia that has somehow built up in the moss. Can it be harmful to my plant? Will it go away? I can't leave the vanda hanging in the tree forever. It gets very cold here in the winter.

Any help with this issue is much appreciated.
