My dog (had 8 years) only pooed once in house because he was sick and couldn't help it.
I have 5 cats. The sisters (2) didn't like when the brothers (2) came, but accepted it, but the male 5th kitten/cat pushed one over the edge. One now sprays on wall to mark her territory (I didn't know girls could do that but she backs up, twitches tail (I've seen it!), never squats, and when you look, there's something on the wall.) (they have free access to outside.)

Anyone know what to do? It's not stinky like male spray but when fresh, does smell like cat pee. Ick.
