I would get an enzyme cleaning product from a pet store. Depending on where the smell is you could try sprinkling it with baking soda and letting it sit for a few hours. The vacuum up all of the baking soda. In other places, a 50/50 mix of vinegar and water with a few drops of Dawn can help. Try that on walls or other vertical surfaces or make a paste with baking soda and water and spread that on if it won't damage the wall. (for example if it's wallpapered). I hope this helps. Wishing you the best.
From? I have 6 . . .
Hi Bea, this is Peggy. We live in the country and have 10 catts (I did not go out and get even one, they were dumped on me), We buy cheap litter from the store and we DUMP it whenever it gets dirty. We do not pick out the stuff. We spray the litter boxes with Lysol when we change them. We also have a dog door and they can come and go as they please. I have had many people tell me they can't believe we even have one cat. I also use smell good electric plug ins. Good luck with your cats, they are wonderful
Nature’s Miracle. You can get it at any pet store or Walmart. Best stuff ever!!!!!
