You can have 10 pets by default.
You can buy 5 slots from the millionaire center
You can buy slots from the cash shop too.
You can use Loyalty Totems to get one additional pet slot.
The plushies used to be the only way to gain additional slots but no longer are used for those purposes. :) Now they're just plushies for collections. There are a lot of different ways to get slots though! Like the aforementioned, the millionaire center sells slots or you can buy them for $20/2000CSC. You can also use your loyalty totems to gain a +1 spot one time per year.
ah okay thank you! how many slots can we have altogether? is there a limit to the CSC slots or the millionaire slots? o
oooh thank you! <3
For the millionaire center slots, there are only 5 right now that you can buy for increasing amounts of sP.
For the CSC slots, I believe the max is 20 right now. You can see a slightly more detailed breakdown on the User Dashboard page: here
I think the limit is 30! The 20 you mentioned plus "X from pet slot plushies and early totems (soft max 10)!" can be gotten by cash shop purchases as well, if I remember right.
Ah, okay. I was just going based off the breakdown as it shows. It shows 20 for the new slots and 10 for the old plushies and such.
Either way, the total max is pretty high right now including everything put together.
