I thank you all for the support. Here are some of my thoughts.

I KNOW some of the reasons they spray. Maybe I do not know them all, and I suppose someone like Nancy might be able to help. But if the reasons are what I believe them to be, then there is no way for me to prevent the "jealousy".

I also have been considering the fact, that just like with us humans on an anti-depressant, one medication that used to work can fail after "x" amount of months/years. So, with that thought, hopefully a new medicine can help the situation.

I would never rehome a know sprayer, I simply could not guarrentee that once in a new environment, that the spraying would stop. I could not dump my problem on anyone and live the rest of my life wondering "what if" the cat would start to ruin their home.

So for now, I will vent my frustrations. But one day, there may not be such a good outcome.

Thank you again.
