The RSPCA is the Royal Society for the Prevention of Cruelty to Animals, a British charity that tries to stop people treating animals cruelly. Unlike many animal groups, it can take a cruelty case to court. It also takes in animals with no home and finds new owners for them. In Britain, people call the RSPCA when they see a hurt pet or an animal left in a hot car. It is about cruelty and care — mostly pets and other animals in human hands — not about wild-bird watching. Scotland has its own sister group with a similar name. In the US the nearest cousin is the SPCA, which is not the same organisation. You say the letters.
