A somewhat difficult enemy to deal with, her moderate health makes her act like a tank but her weak attack power shouldn't be much to be scared of. Her 255 range allows her to outrange many common Rare Cats such as Cameraman Cat, Teacher BearCat and Maximum the Fighter just to name a few. Her rapid attacks make her slightly more of a threat being able to shred your defense if magnified.
The best way to deal with this enemy is with a steady amount of meatshields, around 3 to 4 should work fine, and units that can outrange her such as Cyborg Cat, King Dragon Cat. Tanky units such as Titan Cat are able to tank her hits while also being able to deal a lot of damage.
