Scratch effect Feliway spray against

Our cat scratches in four years (new bed) for fun at the corners. Always repaired, scratched again and again! Spray used and since then no more scratch attacks! Use it for two weeks, hoping the action
continues. But I am very optimistic!
Addendum on 11:11:14: The couch corners are forgotten, spray only once every two days.
Thank you! PS .: New Macken NOT be developed!
