I think it's probably down to the individual cat's nature but ..... our cats have been on dried food all their life ( pet shop had them on it ,moistened with water ,when we bought them as kittens ,no idea how weaned ) and never show the slightest interest in wet food ( weeell a passing sniff at tuna ) . They never go on work surfaces . But cats love amonia smell /bleach so possibly check what you're cleaning work tops with ,in case it's encouraging them ?
