Joe, she had a urinanalysis to check for a UTI and bladder stones, plus
a full blood panel to check for diabetes and kidney problems last time
she saw a vet. What makes you think the results would be different this
time, especially given that whenever she is restricted to one room, be
it for days, weeks or months, she does not urinate?

Depends how long ago that was done, things can and do change.

Do you have a
suggestion how to proceed if it's not physical?


Has she been neutered? ...are you certain?

Is the litter box kept clean? ... cleaned every day?

Is the litter box in a quiet corner where she can go about her business
quietly?

Is there something in your home that may be causing her stress, that the
isolation keeps her from?
