I haven't found a Wedgwood cat like mine, but there are elephants and birds in 'topaz' - which looks to be the same colour as mine. There is wear on the base, so presumably it has some age and is not new.
I've spotted a 'look-alike' for my green bowl in Miller's Collectables Price Guide 2005 p.317. The shape is very like the 50s Murano ashtray by Seguso, except that mine is smaller and one colour only, unlike the one shown which has three colours. This one too appears old with wear on the base.
