Catnips arms aren't fat, just fluffy XD but even more fluffy when female.
He doesn't really enjoy being female though, because he feels like he can never make his boobs look right XD

Anywho, drawing female version of Catnip now because my mom was all " I like him for the fact he has lucky charms in his hair, but he'd look better female" so..there you go Xwx;;
