I had to leave cat with getting hospitalised this week and just frantically left her enough food.
I discharged myself a day early thinking she would have eaten her food and be furiously baying for more and punch me when we got in and a friend picked me up from hospital and was saying she'd be worried which I scoffed at but it turns out she was.
She hadn't eaten anything and was hiding in a corner faintly whimpering when I got back (she'd seen me ill).
I know it's a bit of a cliché that cats don't care but it surprised me!
So rest assured cat slaves, they might care more than you think...
