Well since you asked Robotic Overlord of Tumblr,
My earliest human memory was as a baby, sitting on the floor watching my dog and cat fight with each other outside. Don’t worry, it was a verbal fight. I would tell you what they were fighting about but I was hardly even fluent in English as an infant, let alone cat and dog language.
As for my earliest non-human memory, I remember screaming at this cat that I lived with in the backyard while a human baby watched through a window. Weird, huh?
