I started to feed my cat at very strict times. 0700-1200-1800. And by doing so I stopped her annoying me in the middle of the night. She used to be outside and yell at the window until I let her in. Demanded attention at stupid hours when she could eat whenever she wanted.

Anyway she is now almost 18 and she sleeps a lot. She sleeps and gets candy. And I now have to wake her up at seven most of the time.
