Based on the new image, it appears that the rat may have looked bigger due to the angling of the camera when the photo was taken.
Some have also speculated that the photo may have been edited to make the rat seem larger than it actually is.
The earlier photo posted on Facebook shows the man holding the rat that looked as big as a cat with a pair of tongs.
It is unclear where or when the photo was taken.
According to The Daily Mail, 'giant mutant rats' do actually exist.
Sightings of such creatures have been reported in the UK. Pest controllers have caught rats the size of rabbits in various parts of England and Ireland.
Those humongous pests however, are the far cry from the rat seen in the photo mentioned at the beginning of the article in terms of size.
Take a look at the gallery to see the giant rats.
