Cat Piss.

Someone's cat got into the garage and pissed all in my Barracuda. The smell is unbearable. I'm going to pull out the seats, padding, and carpet this weekend and deep clean it. Anyone ever deal with this bullshit? What did you use? (for the cat and the piss)
Something that has worked well for me are any of the pet urine cleaning supplies at PET stores, not grocery stores. And then follow up with some/any of the hunting scent cover sprays. They kill smells amazingly well.
