I've lived in the coastal regions of the Carolinas, Georgia and Florida all my life, and grew up with cats, and believe me, if that stuff was harmful to your cats, there wouldn't be an outdoor cat alive in those four states!! If you still have concerns, consult your vet, and I'm sure s/he will be able to advise you about the Spanish moss as well as many other organic growths, both indoors and out, that would be harmful to your cats if they should decide to sample it.
