Hillside is now home to over 1000 animals and is one of the UK's most successful campaigning organisations for the animals' cause. We have always known that one of the main reasons animals are left to suffer in factory farms is because people have little or no idea about the immense cruelty involved in their food production. Although most of our rescued animals have been saved from the farming industry, Hillside is home to over 300 horses, ponies, donkeys and mules.
