Horror as man finds five-foot python curled up in the bathroom at 3 a.m.

A man was shocked after wandering into the bathroom in the early hours of the morning, only to find a 5-foot-long python curled up above the toilet.

The uninvited guest had entered the home via a door left open for the dog, before taking a nap.

After discovering the snake at 3 a.m., the man called Snake Rescue Sunny Coast in Queensland, Australia, to come and remove the reptile.

Snake catcher, Ryan Fuller, headed over to the address and posted snaps of the snoozing serpent to its Facebook page.

Carpet pythons are common Down Under, with the Queensland Department of Environment and Science acknowledging they can be “intimidating,” as they can grow up to 13 feet long.

While occasionally found indoors they don’t make a habit of visiting the bathroom, as the site added: “They live in a range of habitats from the wet tropics to near arid desert. Look out for them in undergrowth, in tree branches, or the roof of your house or shed.”

Fuller noted: “Snakes will often come inside looking for shelter or out of curiosity. This is a pretty common occurrence and is why we recommend people keep their doors closed.

“Heading into summer it becomes pretty common for us to start receiving late-night and early-morning calls to snakes that have made their way inside someone’s house.”

And sharing more about their hunting habits, the government site continued: “They hunt by ambush, waiting for their prey to pass by. As they are non-venomous, when they catch their prey, they suffocate it by constricting it and then swallow it whole.”

Fuller told Newsweek it was a carpet python, and while he too pointed out they’re not venomous, they can pack a powerful bite, and even eat small pets.

Fuller said: “We received a call at 3 a.m. from a man who was house-sitting/dog-sitting. He was told to leave the back door open for the dog to be able to go in and out of the house as he pleased, but this also allowed the carpet python to freely wander into the house.

“He was surprised to find the python sleeping on the bathroom window sill with the window sills contents knocked onto the ground and into the toilet.”

Fuller estimated the snake was around 4.9-feet long, adding: “Although a bite can still be pretty painful, they aren’t really considered dangerous. Larger species can and will eat small cats and dogs though.

“The snake itself didn’t pose any danger but most people don’t like native wildlife wandering through their houses unchecked.”

Fuller, who captures snakes without the use of gloves, added: “The snake was sleeping when we arrived. so we woke it up to check its demeanor before simply picking it up and placing it into a bag.” After being bagged, it was relocated back to “suitable bushland,” Fuller added.

The Facebook post, shared last month, was captioned: “3a.m. bathroom surprise.

“After coming in through a door that was left open for a Dog, Mr python didn’t make make it far before curling up and taking a quick nap above the toilet.”

Snake Rescue Sunny Coast shared more information on the species on its website, warning: “Avoid provoking the snake, or making it feel threatened, as it can still cause harm to you, family members and pets.

“Although this species has no fangs or venom, it does have a set of around 100 small, sharp teeth which have the ability to cause substantial needle-like lacerations.”
