Giant rats have been invading homes across the UK over the past year, and more and more of them have been sneaking into buildings through the toilet.
The infestation began in the country's first lockdown last year - the lack of rubbish on the streets drove rodents to empty businesses and homes in search of food.
Experts say the rats are getting savvier as the country opens up after lockdown.
