My parent's cat Sox, who is 22 lbs and NOT overweight (he's HUGE!!) is at the vet right now. Mom said he had been crying since I think yesterday afternoon, and she had noticed some strange behaviour in the litter box. They took him to the vet first thing this morning and he has blocked kidneys.. probably kidney stones but they don't know yet for sure. They have to drain his bladder (that is why he was crying, he had to pee and couldn't!!) and then they will analyse the stones etc to see what's wrong.

Please say a prayer that he's ok. He's about 9yrs old, and otherwise in good health.
