Why does my cat stare at the wall for 20 minutes every night around 9pm?
So this started about 3 weeks ago at my apartment in Denver. Every night around 9pm, my cat just sits and stares at the same spot on the wall near the closet for like 20 minutes straight, and she won't move even if I shake treats. I checked for bugs, mice, drafts, and even put a flashlight up there, nothing. It's always the exact same spot and the same time, which feels too weird to be random. Has anyone else had a pet do this? Should I be worried or is she just seeing something I can't?
