The story
The company closed in September 1997 after a ten-month campaign consisting of daily protests and raids carried out by the Animal Liberation Front, including the removal in May 1997 of 26 beagles.
Following the company's closure, the same group of activists set up Save the Hill Grove Cats, Stop Huntingdon Animal Cruelty, and other campaigns that have jointly altered the nature of the animal rights movement in the UK.
