Fully completed the decor on four floors, and then it just wouldn't give me a new cat. All four rolls were 2 material rolls. The decor makes it more likely to get a cat btw. Also 2 of the floors I hadn't gotten all the common cats. So how? Also know it was way more rolls than that. Just when it reached that many floors it became very apparent. The game just feels like it has fake rolls and wants everything to take the maximum amount of time possible.
