Peeing outside of litter box

I have tried all I can before posting so here it is- I really need help my cat has always used the litter box fine, but this is her second UTI and the medicine is almost gone and she still is peeing in one spot in my bathroom and won't pee in her litter box. I was trying different litters, but have gone back to her favorite (i was trying diffferent because her favorite tracks so much). She was feeling mopey but is now energetic and scratching and meowing again and still peeing in one spot. I have tried Feliway and a variety of household cleaners. Please help with any advice. Also my vet will not test her until her medicine is all gone, but she is acting fine now except with the irregular peeing.

Have you used either an enzyme cleaner or carbon dioxide cleaner on the spot.  I  hadn't tried the carbon dioxide one but it is what Jackson Galaxy recommends, it's called Fizzion.   With the enzyme cleaner you have to soak the area and then let it dry.

I have wanted to try the enzyme because it has been recommended but I have no idea what that is. Are there brands that contain enzyme cleaning qualities or what? I am 18 and live with my mother and she didn't know what that was either. Which ever works best, the enzyme or CO2 I will do

You should be able to find it at a pet store.  The one that is most easily found is called Nature's Miracle.  Another one is called Nok Out, I have had people tell me that they thought Nok Out was the better one of the two but I don't think it is as easy to find.  It is a bit pricey but you have to still soak the area for it to work.

I guess I cleaned that area pretty well but now she is peeing somewhere else much worse. I am cleaning with Natures Miracle but how do I get her to use the litter box?

Try Dr. Elsey's Cat Attract litter additive.  Also, try adding a new box to your home.
