Reply #5: I had a lovely indoor cat who was curious about "outside"...

[Demoiselle]

I NEVER let him go out. Then my dad came to stay with us for a year and announced that he couldn't be bothered to keep the cat inside. (Bothering meant looking around and making sure the cat wasn't nearby when he opened a door.) So the cat got in the habit of quick escape runs, which I ultimately couldn't prevent. This lovely cat, who had lasted 12 years of perfect health inside, finally drank from a puddle of antifreeze under a car parked on our street. He died. I still miss him. And yes, I still feel just a bit bitter about it.
