Fortunately I've never had to use the alcohol/vinegar mixture as my two have good litter box habits. Apparently other people have had success with it...maybe it needs several applications to get rid of the smell.
Thanks for the update. You did it exactly right, fab! Good job! And yes Gizzy is the smarty pants for sure.
I would leave them be and leave their purr pads in place, but since Forest doesn't want the sub box anyway and Gizzy is the more active one, I would leave it out for him since he likes to go in it. Try for a few more days to see if they'll behave themselves. If they have a fight, I would separate them for a couple of days
when you aren't able to observe and supervise. Then try them together again. Hopefully they'll catch on if they fight they don't have each other's company, but if they behave they do. Always give them positive reinforcement for
good behaviour, it doesn't always have to be a treat when a head scratch and "good boy!" feels just as good. Good luck!
