Not likely the Aussie would hurt the cat, but it might herd it!! If the cat has a known escape path up high, shouldn't be an issue. They are smart dogs. Can be high energy, but it doesn't sound like this one is. Most papers will do a free found ad for animals for 2 or 3 days. If you have time, you could call some of the Vets and leave the information. I'm guessing no collar of tags.
Other than that, it's really neat to be loved unconditionally. It's quite different than most cats. Jim.

At a minimum, I'm Pentatoxic...but most likely, I'm a Pentaholic. There seems to be no known cure. Pentatonix, winners of The Sing Off, season 3
