Grumpy cat is really a sensation on Imgur. Born on April 4, 2012, at the house of Tabatha Bundesen Grumpy was one of the four kittens. She was born to a Calico mother but Bundesen is not sure who her father was.
There is some possibility that she is a mixed breed. However, her owner, Bundesen believes that she could be a descended of Persian Ragdoll or Snowshell.
