Sounds like my Pouncer. His is definately stress related and it took a long time for me to recognise his stress. Knowing what sets him off helps me a lot. He's recently had a great run of healthiness, then my college-age son moved back in til he finds a job.... and now I have a stressed out Pouncer.

Some things I learned that stress him:
bad weather
getting locked in the basement
Cat fights (not necessary with him -- others could be fighting together)
MY stress



Get a drining fountain. Fresh flowing water is the best thing for her. Make sure she is actually peeing, because if she blocks its life-threatening.
