Ok, up until now I have never played with overstuffed sim houses. Then suddenly I see all these shiny unicorns, and I feel the bizarre need to hoard them all...as the game rezzes a new one...one by one. Can anyone tell me what mod I need in order for me to get my animal hoarding on?

I saw the NRaas PortraitPanel, but I am unsure if that includes the overstuffing functionality or only the ability to look at/sort all the faces.

Yup, that's all you need One thing though... I believe the current version loses the two column layout you get with pets, so sims and pets will be sorted into one column.

Thanks!!! And that is totally fine about the columns, but good to know! :D

I have a feeling I will be hoarding stray cats...my friends IRL won't let me become a crazy cat lady so young, but now sims will allow me to pretend to be one!

Well, it turned out that I needed to get Master Controller along with the PortraitPanel (for the nice sorting). I'm going to be in hoarder heaven. Yes, indeed...
