Despite the near-infinite number of pet photos flooding Instagram, Facebook and email inboxes, the world just can't seem to get enough adorableness. In celebration of all those cute pets of 2012, HuffPost Green is hosting its annual celebration of the cutest pets that make our lives a little (or a lot) better.
Some pets have even reached celebrity status this past year. There's Oskar, a blind kitten, who won "Best Cat Video" this year, the puppy cams that warmed our hearts, and who could forget the adopted baby sloth in a onesie?
Not all animals receive the same love as these viral cuties. The Humane Society reports that an estimated 3-4 million dogs and cats are euthanized each year in the U.S. alone. Many shelters are filled to capacity and struggle with a serious overpopulation crisis. If you have pets, be sure to spay/neuter them. If you are thinking about getting a pet, consider the long-term responsibility of pet ownership, and explore adoption options with your local shelter, or by visiting Petfinder.com and the ASPCA website.
