The author, who is a rodentologist with a huge personal collection of guinea pigs, knows more about guinea pigs than most vets. The information contained could be vital for the health of your pet, this I have learnt from personal experience. For example, the book covers teeth clipping whereby anaesthetic is NOT used however a vet would routinely use it with the potential death of the guinea pig. It covers absolutely everything there is to know from choosing, housing, feeding, ailments and behaviour. Full of colour pictures and is ideal for the complete beginner or the experienced owner. I can't recommend this book highly enough.
