Female cat and peeing

I have a female cat that is 19 months old. When she was a kitten she would pee in the laundry. If it was in the basket or in a pile on the floor. If a comforter was left on the sofa or floor she would pee on that as well.

When we found out she was pregnant we thought that she would stop nce the kittens were gone and she was fixed. She has been fixed for over 6 months and STILL does it. My son had his jacket on the floor the other day and it was nylon and she still peed on it.

My husband is ready to make her a permanent outside cat. She already goes in and out and she can get into the garage through the doggy door but I don't like the idea of her out all the time.

Any suggestions???

Have you had her in to the vet to be checked for a urinary tract infection or crystals?

When I took her in to be spayed and to get her shots, they said that there was no medical reason why. I thought it was really weird since it seemed to be only fabric. Of course she has already christened my son's new Notre Dame chair that he got for Christmas (that was 60 bucks!) It has a nylon cover on it so I am hoping to take it outside and scrub it down tomorrow.

My dog had a uti one time and she simply peed everywhere!
