The cat urination problem has been solved temporarily, although not the way I wanted to resolve it. Oliver and Tunch got out a window last night at 7, and while Tunch came back at ten, Oliver has not been seen for a day now. He always was the wild one and always trying to get outside, so if he eventually does come back, I may find a good farm for him.
At any rate, the most depressing part is that I was always suspicious that my cats did not like me and just tolerated me, and then Oliver pissed all over my house for two weeks and ran away. What message am I supposed to take from this other than confirmation that he hated me?
