Catlady, That link was very helpful and I am going to try to make some adjustments to Misty's litterbox and also add another box to the 2nd bathroom and see if that helps.

I'd LIKE to know what her vet would recommend but she never did call back at all. I think it's time to switch vets! This clinic has been awful about saying they'd have the vet call me back and then no one ever does. But if I bring in a cat for a check up for a relatively minor problem, they sure aren't bashful about wanting to run $300-400 in tests! I've also been charged more for procedures than what the told me the cost would be BEFORE the procedure was done (like spaying and nail trimming, etc.). I digress.

So, anywho, I am also going to try to Feliway and see if that makes any difference and get all of MIL's bed and bedding washing with cat urine removal that I bought at the vets office when Ozzie had his infection in his peeper.

Thanks for the suggestions folks!
