OT: Fox Urine to deter cats???

I'm sure most here have seen my posts of my crazy cats, and their frequent INSANE aggression and having to re-introduce them. I am doing every thing possible to keep the peace in the house. All the doors are covered with the exception of a few windows that they don't go near that often (although I think I'll be covering those soon too) I have a motion sprinkler in my back yard, and an ultrasonic deterrent. I have also been spraying my front door and porch with straight vinegar everyday, and an extra time before I leave the house. I also ordered red fox urine the other day. I applied it yesterday for the first time. According to the bottle it said only a few drops here and there are needed.

Anyone have experience with this? How much should I apply? How often do I need to apply it?

Thanks for any tips.....all I can say is WOW this stuff smells HORRIBLE!!!!!

 

Good luck.
No experience with it.
