Elvis, our 18 year old cat, died in his sleep last evening. He was walking around when I fed him at 1730. I did not check on him again until I went to bed. He was not breathing. I had taken him to the veterinarian at Cedar Lake Animal Hospital last week. He was off his feed and not perky. She said that he was old with some thyroid and metabolism problems. She was reluctant to give medication given his precarious condition. Now he is gone. I miss that old cat.
