I know what you mean. Reminds me very much of my Minka. It was a Sunday morning, we got up, she played with a ball, had breakfast and went into my bed. When I walked into the bedroom 30 minutes later she was dead. Of course it was a shock for me but it was the best way for a cat to go over the rainbowbridge, probably a cardiac infarction, there was no sign that she was sick before. I don't know how old Minka was when she passed but she lived with me 14 years and was a grown up cat when she was found in a neighbor's garden together with 6 kittens.
Don't feel bad for Chloe. She won big time! She found the perfect home to be the only cat in for the rest of her life. She lived to be almost 18 in great health, had a decline that lasted two days, and passed in the lap of her devoted guardian in no pain or distress at all! I call than a BIG win!! Great life, sweetheart! See you later.
I got word today Chloe passed away peacefully, after 4 happy years as the queen of her house. She would've been just shy of 18 years old. From my friend who took her in and gave her a great life:
"It is with a heavy heart I say Chloe passed away this morning. She went peacefully and quickly I don't think she suffered at all. She stopped eating two days ago I tried tempting her with tuna, cheese and home canned chicken. She seemed ok until last night. I had her in my lap this morning when she died. At least we had the chance to make her last years comfortable. Patty doesn't know yet, she's not going to take this well. She was Chloe's favorite. May tomorrow bring a better day to us all."
