My poor girl cat goes on time out every night when we go to bed. We have to leave her downstairs because she tends to sing pitiful, LOUD songs in the middle of the night, as she walks throughout the house. It's EVERYWHERE, lol. She started doing that after her brother died. I wonder if she's calling for him.
I am also wondering if she is losing her hearing. She does not hear me walking up behind her anymore.

Poor old puss ... it's not easy getting old.
