Lori just wanted to say i completely understand your fustration and stress, since adding the two newbies to my household I have had a few problems now and then too, luckily its not been really bad, and mostly the offending has occurred downstairs, when i just had Lexie and Ash i never had these problems and i have never known who the culprit is,,sometimes you regret your decision, but when those lil loving eyes look up at me , i know in my heart i did the right thing, i just hope something works for you and the kitties, and i know how awful it all can be, here's hoping hon. good luck.
