Just two years after losing my beloved ten year old cat to kidney disease, I have lost another cat far too young. This cat was my sister's, one of a sibling pair that she had since they were five weeks old from the SPCA. Her name was Ling. Her brother Mischkin was very sick with rhinovirus [sp.] when he was tiny but Miss Ling, she was always healthy. She was an absolutely beautiful, elegant little seven year old, balck and white domestic shorthair, beautiful coat and teeth and about 5-6 pounds. I cannot believe any of this is happening, it just seems so surreal. Without ANY recognizable symptoms, our little angel just died this morning. I wasn't there but she was happy, purring, being fed a treat, then she just lay on the floor, stuck her tongue out and was dead within a minute. There was no respiratory distress, no choking, no hindquarter paralysis, no lethargy, nothing. Can anyone help us to understand how we were robbed of this perfect sweeet little girl? Our hearts are just aching, only seven. My sister brought her to the vets right awa- the vet thought she looked like the 'perfect cat' no visible problems. he seemed to think it was a heart problem, possibly genetic. Has anyone heard of such a thing? Just to die in one minute... I can't understand it. her appetite was good as always and she was affectionate, spritely, her usual lovable self. She did get annyoed by her much bigger brother [ trying to mate etc..] from time to time but no injury or distress seemed to be evident. I feel so lost, to lose her so young, any words of explanation or attempts at, would be GREATLY appreciated. Please let me know if I have left out any details. We are sick with missing her. No matter how I go over it in my head I cannot isolate even a shred of abnormal behaviour. Thank- you everyone, for reading this.
