Excessive urinating on rugs by cat

This is a follow up to my previous "Cat Urinating on Rugs"
I took Victoria to the vet and she was checked out throughly. No infections anywhere. She had a Sanitary Shave, and she is a totally different cat. She visits people who come into the house. Has allowed others to pet her. She sleeps with me more now. It's a miracle. the vet thought she was suffering from anxiety or depression. I personally scoffed at both of those. I have not given her an anxiety pill, as she seems to be cured. I now have two cats. I continue to wash her bottom when I can. She is on a diet as she does weight 15 lbs. It's just weird. So Thank you all again for your support and suggestions/recommendations.

Sue and her 'girls: ' Vanessa and Victoria
