Do any of your cats like cat nip? 'Cos I've tried it a few times with mine, and they sniff at it for a while then give me that "eck!" face. To make matters worse, I bought them a 'cat spa' recently, the spa basically has three brushes, a neck rub and a paw pad for them to revel in. And Toffee took a go at one of the brushes, looked comfy enough. So I added the cat nip into the pockets of the brushes as indicated on the instructions. Now she doesn't go near the cat spa at all! And neither does Sandy, but I suspect he never knew what to do with it in the first place!!
