Pygmy hedgehogs were last year's must-have pet.
They are similar to a hamster in that they are nocturnal, enjoy exercise wheels and live for three to five years. They are different because they are carnivorous - and prickly.

However, they are extremely boisterous and difficult to train, so inexperienced owners may prefer to stick with a dog.
