That fucking happened to my cat that was the bomb. Her name was Buckeye, we toke her to get spayed and she had a heart problem and died. First pet the vet had ever lost, is how they say it I guess. When we got her son, whose now our cat spayed we got him a kitty catheter (Spelling?) so if something went wrong they would be right at a big vein to fix the problem. All is well with the younger cat to bad BUckeye died .
