Strangely enough, this unit has slower movement speed than Cow Cat and it's miles behind the cat unit version. It deals heavy damage, but has quite low health and is single target.
A stack of midrangers such as The Flying Cats with support from A. Bahamut will kill it fast, but be careful of the large numbers! It is usually recommended to stack as many damage dealers as possible to prevent a big stack of Crazed Cows from forming and overrunning the feline frontline.
