They are one of the most popular pets in Britain. And one of the most colourful!

It's worth calling in to the marquee just to see the huge range of cavy types. And if you want to know more, there are plenty of experts and enthusiasts on hand who will be more than happy to chat.

There are classes for self coloured (single colour) and non-self (various colours). And there's always a pet section. They are judged in three age groups: under five months, five to eight months and adult.

Most entries in self classes are black, white, golden and cream, with others such as chocolate, lilac and red in the any other colour class.
