Cat Causes Big Stink - Causes Carpet Replacement

Hi All:

My 05 Prius (w/108,000 miles) carpet was er, uh, peed on by our cat which got out of the carrier while being taken to the vet.

Numerous DIY and professional attempts have been sadly unsuccessful in ridding the carpet of the cat pee odor. I called our local Toyota dealer and they quote me $600+ for the new carpet and at least another $300 or so for removal and replacement.

I'm seeking ANY ideas on how to get a new or near now, non-stinky, new or like new Grey 05 carpet assy. PN# 58510-47200-B0 so I can either do the job myself or take it to my local stereo shop, who's already had the entire interior + carpet out to Dynamat the whole inside, to perhaps remove and replace the stinky carpet.

I did find it for $420.76 here:
CARPET ASSY, FLOOR, FRONT. MD.GRAY,TRIM1#. MAT & CARPET. TOYOTA PRIUS 1500CC 16VALVE DOHC EFI (2004 - 2006) # 5851047100B0, 5851047070B1, 5851047200B0


Any suggestions on where I can get this OEM carpet at a much reduced price?

Thanks for your time!

Happy Scent-Free Motoring!
