Best way to Remove Cat Urine from carpet?!?

You need any enzyme based cleaner. Get a black light to find all the spots.

Good Luck

Yes, I used Nature's Miracle Citrus scented. It's not cheap but not super expensive, either. I've seen it mostly at Petco or Petsmart but it may be in grocery stores now. I had to use it with my elderly cat. It usually takes a few applications to get the smell completely gone.

tear the carpet and padding out.. and replace

you may have to even clean or replace the subflooring underneath.. as odds are, the urine has soaked thru the carpeting and padding and into the subfloor.

Get the prove it kit you can also try floor dry and urine removal spray
