Sniper has been AMAZING. I was able to completely remove all the feral cat urine scent from the carpets, mattresses, clothing, and toys. It worked beautifully and left no smell, no fumes, and didn’t leave any discoloration. Sniper is now my cleaner of choice and I use it everywhere to clean and sanitize as well as freshen the air. I even use it in my daughter’s gym shoes and soccer bag. Thank you so much. Seriously the best product on the market.
