Brass Rat Statue with offerings in a Hindu temple in Kathmandu (Nepal)
In Hinduism, the rat is Ganesha's Vahana ("vehicle" or "mount"), and some Hindu sects worship this rat.
This lead to the misconception that Hindus pray or worship a Rat God.
In any case, there is nothing wrong in respecting and worshiping any sort of animal.
For more information about the rat as Ganesha's vehicle, read this section of the Wikipedia article on Ganesha: en.wikipedia.org/wiki/Ganesha#Vahanas.
Photos taken during a motorcycle trip with a friend in Nepal in March 2013.
This includes a trip up the Kali Gandaki valley to the Annapurnas and the Lower Mustang region, with its beautiful Himalayan landscapes.
Those photos were taken one year before the April 2014 earthquake that killed many and caused major damage in central Nepal.
Many of the buildings and temples on those photos have been damaged or destroyed by the 2014 quake, especially the shaky brick houses in Bhaktapur.
