I have some handmade oversized floor cushions. While I was in Iraq one of my cats was upset by my absence and illustrated his displeasure on these cushions. I've removed (and tossed) the pillows from these cushions and took the cushions to the dry cleaner with the intent of replacing the pillows once I got the cushions back from the cleaner. Unfortunately even after getting the cushions cleaned, there is still a cat odor. Does anyone have any recommendation on how to get the smell out of the cushions?
