More Pee and some barf

I found some interesting pee- on this radiator in the living room where jake used to pee all the time because he would sit on it and look out the window and see this other cat who could still get into our yard (we put up some serious fence) and then he would pee all over the radiator. So it's been a while since he peed there. (BTW- cat pee on radiator in summer- bad. Cat pee on radiator in winter- I WANT TO DIE _ HELP! I scrubbed it like crazy with Nature's Miracle. Toby then threw up twice- I cleaned that up.
