I know what it's not, so now what?

Hey folks! Happy Holidays, and if you don't believe in Holidays, enjoy your time off!

I've been on here asking questions about my cat, and though you guys have done your best to answer, none have been the correct answer! So now here's part 3 or 4 to my question.

My cat seems to have a thing about peeing on rugs or mats ( 6 yr. old female, fixed, shots up to date). Some suggested various sprays or other potions, some said take her to the vet, or it could be her social setting ( no other pets, no kids, just the wife and I. Had her since birth.), or some other problem. Well I finally figured it out! The one thing that all of these rugs and mats had in common is; rubber!!! After giving up on buying new mats, the wife and I purchased another set today and guess what?! She peed on it! So my question is; does anyone know why she would have this obsession with the smell of rubber and is there anyway to break it?! She doesn't pee on anything else and we stay on her box like a cop on a drunk driver, so what gives? Wives like rugs and mats and I need help on how to stop my cat from doing the deed on them all the time! Thanks!
