I have been blown away on how good this product is...Previously I used another product which removed the stain however it left a very strong citrus smell like off lemons...was not a fan...So when I ordered the PetLab stain remover spray I was extremely happy with the results both stain wise and smell wise...Caring for a cat with special needs accidents are inevitable...However along with Scottys washable toileting pads and now this product...things are much easier to manage...I have ordered the concentrate that makes up several litres...this product is a game changer.
