Teach a man to fish, and you'll feed him for life. Give a cat a box and you'll... give it hours and hours of fun? There's something amusing and adorable about pets trying to fit themselves into things they're obviously too big for, so you bet we love this video of Maru the cat. No words can describe how cute this clip is; you'll just have to see it for yourself!
