School supplies cats need

[Angel's Human]

(As translated by Marylin Peterson, expert pet translator by experience.)
I think that most cats shouldn't have to go to school, but the ones who should need needle-like teeth, meat hook claws, and their own definition of intelligence. Along with those things, they need grudges. For example, I, Patch, hold some form of grudge against the following:
-mice
-rats
-bugs
-moths (not the same as bugs, before you ask,)
-computers (or what eve they're called)
-dogs
-keyboards
