Hedgehog turned out to be conker.
Every 24 seconds, a member of the public calls the organisation to report possible animal cruelty or suffering.
While most of the 1, 279, 953 calls this year did result in rescues or investigations, some turned out to be either hoaxes or cases of mistaken identity.
The organisation has issued a plea for the public to make sure their concerns are valid before telephoning in.
Among the bizarre examples of mistaken identity in calls received this year are a conker mistaken for a baby hedgehog, a carrier bag flapping in a tree mistaken for an exotic animal, and a patio chair mistaken for an injured swan.
