I actually loved this one, took me a while to work out dude. I came up with all sorts of answers but one just stuck the entire time!
Is it a kettle with ants in?
Nope. Here is a clue though. Most of the riddle is a metaphor. The windows for example aren't windows at all, but holes. I'd say the only parts that can be taken literally is line 2 and line 4.
