I am a pet collector and i think KI should increase the limit for pets in home. I do not want to buy a new house every time my home is limited with 50 pets. I think KI should increases it to at least 100. When i buy potion in crowns shop it only works for items.
A house with multiple zones might work. The outside could be broken into separate areas, so only one group of 50 would be loaded at a time, but there could be more total. You could have a back yard and front yard. or a courtyard, cave, or even multiple islands bridged like floating lands, each with individual inventory.
