This cat seems to be in mouse hunting mode.
“I’ve had enough of you! You lousy mouse!”, it thinks to itself.
“You’re such a creepy creature! You think that, because it’s dark in there, you can hide from me”.
“Oh, yes, you can try to hide in the dark, but you will never manage to run away and escape from me”.
“I’ll show you who’s in charge here”.
“I’m coming to get ya, and you’ve got nowhere to hide”.
“I swear to the fine brown hair of my gorgeous striped tail that I’ll make you regret the moment you even thought of entering the warehouse that I guard”.
“Because this is the duty that humans assigned me, that is to get rid of any little creatures like you who dare trespass this well-guarded property”.
“So, watch out, because I’m coming to get ya, just like in the lyrics of the House of Pain song: Jump Around!”
