As long as you keep sobriety your #1 priority, all things happen for a reason, but like Dee, omens to me can be made into excuses to allow things to happen that are totally in our control.
I am sorry about the cat, but the lose of a cat in the grand scheme of life is only signifigant for a short while. Being upset is part of recovery if we deal with it and learn from it. When drinking I had ever excuse under the sun to drink, today I take responsibilty for my decisions and actions.
A huge part of recovery is learning how to use a different solution then a drink to deal with what life throws at us. Bad things happen in sobriety, how we deal with them determines if they get better or worse, I personally have never heard any one say that problems were solved by drinking, they are either made worse or they are prolonged.
