My cats live up to 15 years. So, anything past 10 years is a good life.
Funny how they use the words "May Cause!"
You're treating them right, that's for sure. I had a cat named Herb that I finally had to put down after 19 good years..he was still healthy but getting dementia so howled day and night...after two years of no sleep, I regretfully put him down. My husband had been a pipe smoker....constantly ringed in smoke...Herb seemed to like it. Guys had me outnumbered on that one. Cough, hack.
