Catwalk makes a nice change from the usual run of violent computer games, because here you play a night-prowling cat, whose harmless interests include pouncing on - and eating small mice and birds - well it's nature anyway! Suitably, you have nine lives and nine screens of varied action to get through, munching on fur and feathers all the way. There is a very good demo which shows you all the screens, taking you from home, through a building site, the graveyard, to eventually end up in a missile silo, of all places. In each of these different locations there are either birds or mice or both to be eaten, and all the screen must be cleared before progressing to the next. There are also hazards like night prowlers, witches, ghosts, moggy bashers and the like.
On the fourth screen the pace changes as the fauna vanish, but in the factory there is a large pile of cat food tins to be reached. Each screen has its own graphics to identify it, and in some respects, each screen makes for a different game.
