Is the cat neutered/spayed? What damage did it do? Holy cow, I hope it finds a new home...not sure what kind of owner the lady is.

Call the Humane, vets, anyone you can think of. Borrow a live trap from one of them. Leave some stinky tuna in the trap, or outside.

GOOD LUCK!

And catsitting is a joy, with the right cat. I think it's best to visit them in their OWN home, twice a day, for feeding, and 1'2 hr of attention and play! DOn't give up...just go to the cat, don't keep it in your place. Easier on everyone.
