This naturally effective cleaning product uses biological ingredients including enzymes and bacteria to remove urine stains and bad smells. Urine Off Odour and Stain Remover Spray for Cats will even treat old urine stains, without leaving any residue behind, and it is safe to use around humans and animals.
