Ms Russell, who lives in St Clair, gave Kristie a guinea pig as a pet, but took over the duties of looking after it when it became obvious that Kristie was allergic to the cute little critter.

As a result, Lyn Russell was recently crowned the National Cavy Show champion in the Riverina region. The provenance of the word ``cavy'' is cavia, the Latin for ``guinea pig''.

Ms Russell won two out of the seven categories for best in show and best ticked, as well as the overall award, where she beat exhibitors from all over Australia.

``It was a big surprise,'' Ms Russell said.

She's been exhibiting guinea pigs for four years and now has more than 40 different breeds.

A lot of hard work goes into getting the guinea pigs into top condition.

Judges look at the crest, colour, shape, coat, ears, eyes and condition of each guinea pig.

Ms Russell spent two weeks grooming her prized pets to award-winning standard.

``You have to be very dedicated,'' she said.

``You have to remove all the guard hairs from the cavy so that the coat feels soft and silky.

``This alone can be take up a lot of time.

``They also have to be washed squeaky clean and have their nails clipped.''

People interested in exhibiting guinea pigs are invited to the NSW Cavy Club show at Castle Hill Showground's George Bell Pavilion at 10am this Saturday.

``They are great pets for children because they are inexpensive and easy to look after,'' Ms Russell said.

She hopes to defend her national title next year.
