grumpy cat: has died
RIP Grumpy Cat. You were too pure for this world. I will spend all day being grumpier than usual in your honour. pic.twitter.com/WYWfFvaJea— Rachel Hawkins (@ourrachblogs) May 17, 2019
This might sound pathetic, but I'm really sad to hear that Grumpy Cat has died. I'm a serious cat lover, and fairly grumpy myself so GC was a source of great joy. Hugging my own cats a little tighter today, much to their distain... #grumpycat pic.twitter.com/gkUJYq9z5K— Captain Twitchy (@captaintwitchy) May 17, 2019
