When the builder discovered a tiny pup on a building site in Speke, Merseyside, he knew he had to help. But once he got the animal home, he discovered to his surprise that he had actually taken home a fox cub.
Once he realised the animal's true identity, the builder contacted the RSPCA.
The little cub was taken to a vet to be examined and given some puppy milk. He was then transferred to the RSPCA's Stapeley Grange Wildlife Centre in Nantwich.
Once he's strong and independent, he will be released back into the wild. Female foxes often return to collect their cubs.
Leave cubs well alone
It's quite common for older cubs to be on their own during the day as they learn vital survival skills. If you find a fox cub alone and with its eyes open, it's probably fine and their parents will likely be nearby. You can leave out some water and puppy food if concerned.
But if you find a cub on the road or somewhere open, move it to somewhere safe and sheltered close by. It's crucial that you handle the cub as little as possible.
