Bert,
I take in abandoned strays usually from my vet's office. They live out their golden years in luxury and die peacefully. Poor Susie was a kitten who died from cancer. Lucifer died of a heart attack - congenital heart defect (Yes I had an autopsy done) - while I was out of town. The first rule of my home which is presented to all who enter is "The cats can do no wrong". Everyone laughs until the cats pee on them in their sleep or vomit in their shoes to show displeasure and I nod knowingly and say "The cats can do no wrong". They only do these things to people who annoy them. And I have given up trying to teach them manners.
Mary
