Don't mix well, which is what I was counting on earlier today. I was hanging out inside and heard the distinctive sound of two cats that don't like each other, or where the other one is hanging out. I went out to see where they were and they sere off the east end of the deck, so I went inside to grab a pitcher of water. When I got back out, they had moved to under the deck, so could then be reached with the hose. As I had suspected, I was able to convince the non-orange cat to leave the area with the mere idea that it might get wet any second.
Nope, no pictures, averting bloodshed was my one and only priority.
