One starts to lose sense of time if they are stuck in the same isolated room for a long time.
How many days has it been? How long have you been stuck here? Is anyone who remembers you even alive? Is there anyone looking for you? So many questions, but there had been no answer.
To the isolated mind, they fail to comprehend the passage of time, they even lose sense of their environment, unable to notice the changes, the deterioration that their cage had gone through.
They even failed to notice that the lock to their cell had long rusted, making it impossible for any key to work on it.
That was the state of the Cat named Catt0. A being so old that even the First Knight holds some respect for it, but it was this age that became the poison for the little cat, who is ignorant of the state of things and did something entirely pointless.
Isn't it funny? Won't you laugh about it?
