One of my nicknames for Goof is Canary Cat. Are you familiar with the story of canary birds acting as warning systems for coal miners? For many years, into the 20th century, canaries would be used to warn miners of toxic gases; the poor things would get sick and keel over long before the bigger humans.
Well, Goof doesn't warn me of toxic gases but he does warn me when I'm getting sick. Whether it's an impending asthma attack, pneumonia, or the stomach bug, even before I feel sick he starts cuddling up to me and sticks to me 24/7. I joke that I'm going to call work and say "I can't come in today, the cat says I'm getting sick." As I get better, he starts moving off and spending less time with me. No other cat I've had has done this, just Goof.
Does your cat keep you company when you're not feeling well?
