Do I need a home ?

It's possible, but assuming you want to be able to enjoy them in world, it's more complicated.

You can have them live in The Cattery, but you have to buy separate food for there, and you will need somewhere to rez whenever you want to bring them back in world to interact with them. Example: you need to rez both to pick them up and to put them down, even if you are cuddling/wearing them in between (and wearing portable food). And you should not intentionally log off while wearing them as they can't eat and could get sick or even break.

Search for "sandbox" or SIMs set with a longer return. You can probably find places that give you enough time to transfer them to the cattery or back, but somewhere that you can watch them play is going to be a lot harder. Example: I know of a SIM that has a 5 minute return so that people can use it to rez boats for sailing, but that is considered a long return time. I've also seen sandboxes with 20 minutes or longer for builders, but they frequently close down or move, and I've honestly not used one in a very long time. Also, some SIMs will let you rez there for longer (but not leave things there) if you are a member of their group, but you may have to pay to join the group.

If you think about renting a small place, remember that each cat is 13 prims plus attachments. You can but them in low prim mode, but you have to take them out of low prim mode in order to pick them up or for them to be able to move.
