This topic makes me sad.

I have read information about it, and it breaks my heart.
Willow is 16 1/2, and she shows no signs of issues with being forgetful/getting lost or anything along those lines, but she has gotten more vocal and wants to be with me a lot more. During the night, she comes to me several times. She walks all over and around me. She often wants me to pet her nonstop. If I stop, she will tap my face with her paw. If that does not work, she will meow loudly. Some nights, it's really bad, and I struggle to get any sleep. During the day, she sometimes decides she needs love and will come and sit next to me. If I don't pet her, or if I do but stop, she starts meowing loudly until I pet her again. Makes phone calls difficult. I was gone one day while some work was being done in the attic of my house, and my husband was home. He said she was meowing so loudly that she could be heard up in the attic, and she was doing it nonstop. Nothing he could do to get her to stop. I ended up just going back home. Once I got home, she never meowed again. She also meows loudly the entire way to the vet and even once we get there and are in the lobby. She is itty bitty, barely 7 lbs, but boy can she meow strong and loud! She was never this vocal or needy when she was younger.
I love the little girl so much and have gotten more and more attached to her. I have lost so many cats before they made it to her age, so I live with a degree of worry about her. I hate it that she is getting old, and it is going to tear me apart if/when she starts having issues where I have to watch her decline.. and let's not even talk about losing her.
