Guinea Pig Appreciation Day only started last year, but it would be a huge hit in my library as the young children I teach love guinea pigs and I am constantly asked for guinea pig stories. Fortunately we have a large number and some of them are series so they can 'get hooked' and keep reading. Humphrey's Tiny Tales by Betty G Birney have been popular and the graphic novel series Guinea Pig Pet Shop Private Eye by Colleen A F Venable has a large following too. We used to have a wonderful Folkmanis guinea pig puppet too, but sadly he was borrowed, never to return. I do know he is probably well-loved! The display does work without accompanying toy or puppets.
