This December 1, 2015 photo shows Grumpy Cat posing for a photo during an interview at the Associated Press in Los Angeles. Animals can melt the human heart, tickle the funny bone or bring us to tears. There is no end to the number of online animals – from YouTube to www.explore.org and all the social media sites in between. Nobody was busier than Grumpy Cat in 2015 and that probably won�t change.
