A seven foot long python was left abandoned by its owner in a cardboard box in Sneinton.
The snake was discovered curled up in a box by a shocked passer-by on Monday (October 9).
They contacted the police, who took the snake to the RSPCA’s Radcliffe branch.
The snake has now gone to a specialist exotics vets to be cared for and it will later be moved to a rescue centre for re-homing.
The RSPCA’s Chief Inspector for Nottingham, Simon Parker, said: “Sadly, this isn’t unusual.
“We are finding that many people are unaware of how much of a commitment these animals are when they take them on, which we believe may be why we are rescuing hundreds of reptiles every year – and this number appears to be on the increase.
“Snakes are completely dependent on their owners for the correct accommodation, heating, lighting and feed, all of which must replicate their wild habitat as closely as possible to keep them healthy and allow them to express their normal behaviour.
“Without proper care they can suffer from serious diseases, dehydration, injuries, parasites, and in severe cases or if left untreated, they can eventually die.”
In March a boa constrictor had to be put down after being found in appalling conditions in a box in St Ann’s.
RSPCA exotics senior scientific officer Nicola White said: “We are seeing a worrying number of snakes coming into our centres, because owners are no longer able to care for them.
“The main thing we want to stress to people who are thinking about bringing an exotic pet into their family is to think before they buy – research the needs of the animal thoroughly and make sure that you can provide everything that animal needs for the animal’s entire life.
“We would encourage potential owners to read books written by experts on the particular species they wish to keep, to join member societies where there are experienced keepers who can help if you are struggling and specialist vets are an excellent source of support and advice for owners.”
