ok so I'm going to propose that if you want a character with a mental disorder you must research it. you have no buisiness having a character with some sort of disorder if you don't know exactly what it is, how it looks, etc. like depression and self-harm. that crap needs researching. we don't go and cut ourselves bc someone told us we couldn't have a bowl of ice cream because theres none left. i've seen people rp self-harm over simple things like that and its gross. i have a history of self-harm so if people make their cats harm themselves over petty crap like they couldnt find a crow feather for their nest i will flip my lid.
anyway.
If you're going to give your cat a disorder, please research it so it can be portrayed accurately without offending anyone who actually has a/that disorder.
