Facebook is not a waste of time: it saved my cat.
Not long after my good friend Jim Davies shared a story about his beloved pug's sudden illness, I came home to find our beautiful cat "Loki the Loquacious" turned lethargic, not interested in food, and yowling at touches to his abdomen. This struck me as seriously unusual, and I was motivated by Jim's experience to look up Loki's symptoms.
The recommendation: take him to the vet right away. So we did.
It turned out we were right not to wait: this was a life-threatening urinary blockage which could have killed him through cardiac arrest. According to the emergency room vet, this is a particular issue for male cats near the end of winter, when for some reason they drink less. This leads to increasingly concentrated urine, crystallization of debris in the bladder, and, thanks to the (ahem) tapered nature of the male cat anatomy, can lead to blockages that can kill a cat in under 72 hours.
Fortunately we caught it in time, and they were able to catheterize him, put him on an IV and antibiotics. Loki started out as a feral near-bully cat, but after years of love the vets pronounced him a sweetie.
They thought he would be home after a couple of days, though it was closer to five. But he's home safe now, and that happened because me and my friends were on Facebook, sharing our stories.
Jim, if you're reading this, as I said on Facebook: I'm sorry for your loss. But thank you for sharing it. You helped me save my cat's life.
