If you're relying on a cat to get you out of bed every morning then maybe you should just get an alarm clock (or change your lifestyle). But if you're relying on a clock to get your cat out of bed every morning then get a MeowCoo Cat Clock. The cat wont 'meow' through the night, but due to its inbuilt light sensor it will switch off in the night and come back on when the sun shines to wake you (or the cat).
The MeowCoo Clock is a cuckcoo clock, but instead of a cuckoo it has a cat (believe it or not). So every hour you will hear a Meow!
The MeowCoo Clock requires requires 1 x AA battery for the movement and 1 x D battery which makes the cat pop out every hour
