Ah, AmericanEagle, I see you are truly one of us! Cat addictions last a lifetime, once smitten.
I love the way people write about their cats. So much affection, enjoyment & respect for these darn critters that take over our lives!
Rolland sounds like a wonderful cat. It's terribly sad when something like that happens, I know .... But we never forget them, do we?
Oreo & Midnight sound a delightful pair! Obviously Midnight knows what his job requires in your house: entertainment!

He sings for his supper!
Do you think their was some foul play in the disappearance of your cat, Rocky? One of the worst things, I think, is when a pet disappears & you have no idea of what's happened to them. I know, it's happened to me. Extremely sad.
