Shocked home-owners in Basildon found a metre-long snake as they renovated their new home in Sorrel Court, Basildon.
The snake was discovered after knocking over a lit candle in the bathroom. It was identified as a rat snake which are not venomous.
The reptile was eventually found in the top of the toilet, where it had been dyed a slight tinge of blue from the cleaning products used in the cistern.
Homeowner Naomi Burdett said: "My partner discovered the snake after hearing the candle smash, he saw the snake which hissed at him then backed away into the toilet."
He ran upstairs in a moment of panic, neither of us are the biggest fans of snakes and it’s not exactly what you expect to see in your downstairs loo. >
They were able to contain the snake until RSPCA animal collection officer Joe White could attend.
I’m sure these poor people got quite a shock when they discovered a snake residing in their toilet.
He said rat snakes are kept as pets fairly regularly in this country and that this one was likely to be an escaped pet.
Anyone who recognises the snake is asked to call the RSPCA inspectorate appeal line on 0300 123 8018.
The snake has now been logged on Pets Located and is recovering at a local wildlife hospital to be monitored in case he has ingested any of the chemical toilet water.
