Well, over the New Year holiday we accidentally locked an outdoor cat inside while we were out of town. Initially, I was very happy that she had not peed on my bed or clothes. I thought she was so clever to use the tree. The first thing I did was to get the "clumps" out of the pot, took the tree outside, and ran several gallons of water through it. I was hoping the action would be like the rain and rinse the pee out. I then topped it off with some fresh soil and brought it back inside.
Here I am about 2 weeks later...and leaves are falling, falling, falling....

Does anyone have any ideas about what might save my plant? Perhaps more rinsing, or totally new soil? Or is the poor thing a goner?!?
