This butterfly-like witch attacks by throwing red couches at a decent distance. Her attack can wipe out most small cats and some medium cats in one hit, so it is still best to keep an ongoing meatshield of smaller cats to protect any larger heavy hitters.
It is recommended to use any cats that outrange this unit and keep them protected by using any smaller and cheaper cats. In the long run, defeating Gertrud should be not be much of a sweat.
Also, you can speed up the fight by using both Chibi Madoka and Chibi Homura to activate a Cat Combo that is probably called “Best Friends” in English. It will greatly ampliy the “strong” effect against the boss.
