Amber has tons of cat toys and brushes. She plays with none of them (barring one mangled old toy mouse that she has ripped all the fur off of!! So it's now just a lump of plastic

)
She loves string, show laces, boxes, empty loo rolls and kitchen rolls but she adores plastic bags (Sainsbury's in particular - she loves the orange bags??

) Our house is a happy place when we get the online shop done, Amber spends hours playing with a pile of carrier bags... she hides under them, drags them around, rolls about in them and then crashes out for a nap on top of them
As for cat brushes, we bought some 20p tooth brushes from Morrison's and Amber will jump through hoops to get a brush from one of those!!
