As the stage starts, Ultimate Bondage Cat will spawn, and it will keep on spawning during the battle. Up to 6 of them will spawn. Squire Rels appear as distractions and Ginger Snaches will appear as support.
Both the Squire Rels and the Ginger Snaches are easy to kill, so your main worry is about the Ultimate Bondage Cats.
This level can be beaten with a simple strategy.
Start the stage by leveling up your Worker Cat and saving some money. When the Ultimate Bondage Cat gets near, start spawning your Paris Cats. After a bit, start spamming your meatshields, Parises and Bahamut. Do NOT give a stop to the spawning of ANY of these cats, and you should be fine. For Ginger Snache, your Parises should be able to handle them easily, and the Squire Relsare not any problem.
