As the stage starts, Ultimate Bondage Cat will spawn, and it will keep on during the stage. Nearly 8 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 Ultimate Bondage Cat.
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 Cat. After a bit, start spamming your meatshields, Paris and Bahamut. Do NOT give a stop to the spawning of ANY of these cats, and you should be fine. For Ginger Snache, your paris cats should be able to handle them easily, and the Squire Rels are not any problem.
