Everyone on the internet seemed to know who Loki was - and today, the whole world is saying goodbye together after Loki suddenly and tragically passed away.
Over the past few days, Loki was having trouble with his kidneys. He was diagnosed with chronic kidney disease over a year ago, and when it started acting up, his parents immediately took him to the vet. They set up a GoFundMe to help raise money for Loki's treatment, which has since raised over $34,000. He was put on dialysis and the doctors tried everything they could, but unfortunately, 5-year-old Loki didn't make it.
