A bearded dragon was found "cold, weak and unresponsive" after being dumped in a park in a shoebox.

The exotic pet was found abandoned in a cardboard shoe box by a resident in Mansfield Park in Chingford and the resident took the little reptile home and called the RSPCA for help - sparking an appeal for information from the animal charity.

RSPCA Animal Rescue Officer Nicola Thomas said: “This poor, abandoned little dragon was cold, weak and unresponsive.

“I rushed him to a specialist vet who gave him a thorough examination. They found a weakness in the beardie’s front legs, suggesting a calcium deficiency - which is a common problem for reptiles who have not been looked after appropriately.

“I was really worried about this little chap, but after getting treated with calcium, happily he perked up. He will now stay at a specialist boarding facility where he will continue to be treated and hopefully, in due course, he will be rehomed. If anyone knows anything about this abandoned bearded dragon, we would urge them to contact us on 0300 123 8018.”

Nicola added: “Sadly it is not unusual for us to be called out to collect abandoned reptiles, and this incident highlights the challenges of properly looking after an exotic pet. Many people are unaware of how much of a commitment these animals are when they take them on.

"We would urge prospective owners to thoroughly research the needs of the particular species and what is required in the care of the animal, using expert sources, and only consider keeping one if they can ensure they are fully able to provide for these needs.”

An RSPCA spokesman said: "Reptiles may look resilient and tough on the outside but they are actually completely reliant on their owners to provide the correct environment for the species, including heating and lighting, and an appropriate diet - all of which are essential to keep them healthy and allow them to carry out their natural behaviour. Without proper care they become ill or suffer and, in severe cases or if left untreated, they can die.

"It is not always easy for an owner to tell when they are ill, fearful or suffering and by the time they are taken to a vet, if at all, it can be too late.

"Abandoning a reptile or releasing unwanted exotic pets into the wild is cruel and illegal, as most exotic animals kept as pets are unlikely to be able to survive in the wild in Britain. If you do find yourself in a situation where you can no longer look after your pet, there are options available.

"You could contact the original seller or a local reptile rescue centre for help rehoming your reptile if you feel you are no longer able to care for them."
