Good time waster but far far far to grindy and filled with an insane amount of ads ( I have a weakness so I bought vip.. which in itself is far to expensive) . By the time you reach the second cat house you will need some LVL 6 managers which costs a stupid amount of fish. Or you will 3+ manager that are LVL 3+. Doesn't sound to bad right? Wrong. The epic tier production managers are super super rare and if you decide to just buy them. An upgrade from lvl 1 to 2 is 15 dollars in just gems alone.
