Thanks for the reply catlover2!! But it was a big puddle of pee not spray. Does that matter?
We've seen these friends before and no inappropriate elimination ever happened but that was before we separated them. So you're prolly onto something. I can prolly use a garbage bag (or 2) to put under the throw blanket for a couple days, cuz that would be a big waste of tin foil. Forgot to mention, he had peed right by my leg. So that must be a sign for something...
So when we go for groceries today I will get some garbage bags and put them under the current throw blanket and hope for the best!
