Bests & Worsts Reviews from Amazon

This works. There's an important step though - do it WHEN the cat is watching and close by the item you are spraying, I did it when I saw my cat meandering around getting ready to claw then sprayed the chair with her right there. She did an equivalent to a nose-wrinkle in cat language when I did this but she did STOP scratching. IMPORTANT: If you do it when they are not around they will not associate the negativity of a spray to the scent and will still scratch. Cats HATE anything that sprays. Just make sure to RESPRAY about every 2 weeks, WHILE the cat is there close and watching - that makes a huge difference for them to observe you 'marking' it for yourself and therefore they see you removing what they thought was their 'toy' ownership. In turn, (while cat was watching) I then rubbed some catnip on her cat tree, petted her for positive reinforcement which ensures she understands her 'toys' from my 'toys.'
