Animalcolm by David Baddiel

Malcolm doesn't like animals. Which is a problem because his family love them. Their house is full of pets. What the house is NOT full of is stuff Malcolm likes. Such as the laptop he wanted for his birthday. The only bright spot on the horizon is the Year Six school trip, to....Oh no. A farm.
 
Over the next few days, Malcolm changes. He learns what it's really like to be an animal. A whole series of animal, in fact...
 
It does make him think differently. And speak differently. And eat differently. And, um, smell differently. But will he end up the same as before? Because sometimes the hardest thing to become is yourself.
