In a now-deleted video, Paul claimed the rats had been carried there by his dog - though his assistant later admitted to placing one there - and he pondered aloud how he would get rid of them.

In a shocking move - literally - Paul stands above the rats and yells, "No rat comes into my house without getting tased!" before unleashing 50,000 volts on the deceased animal.

After they're thrown in the bin, Paul then tasers their bodies again.

Earlier in the YouTube clip, Paul had lifted a fish out of a pond in his garden and pretended to give it CPR. While it was already in a weak state, removing it from the water was unlikely to have helped its cause, and it's believed to have died.

Twitter users have been swift to condemn the clip.
