It`s a great compliment, hearing that from a cat lover like yourself. And yes, you have to build a lot of litterboxes to keep up with all of their pooping. After you handeled their poop you can think ybout selling them some cookies or maybe some catnip, you know... for the fun ;) There are also other rooms you can unlock with each stage. We will continue working on it for the next weeks.
Glad that you liked it ＼(＾▽＾)／
