I strongly believe that animals keen noses can detect something in the urine that tells the sniffer that the urine in question is from a carniviore. Possibly the protein traces.....IDK. I have watched the reaction of animals to different types of urine, in hunting situations . From my VERY limited experience, individual animals react diferently. Some go on alert, some don't. But none that I have ever seen actually run away as if they were truly spooked by it.

I think the use of human urine as a deterrant may work, but I'd NEVER bet a crop on it, myself. Use C-4 on tripwires for sure-fire deterrants:thumbsup:
