Yep, have felliway too, sprayed it all over the settee when I got it but next day he'd sprayed all along the side, he's obsessed.
I had throws over my last settees but as you say Susanne they go underneath and scratch, li'l butter, I hated having to constantly straighten the darn things, they didn't really help much and I think I would prefer wiping the side of the sofa every day. I will look out for the 'sticky paws' and the pet training spray, thanks and I'll let you know if it works,
