None of the above for me, none fit completely. Closest is number 1, but they all have names (it's only takes me 5sec to think of one so they have one). And they do come out to chill once in a while, but I do breed them for money, not just to cover cost. It's a fun job, that also involves my pets.
Just because you have 100+ doesn't mean they become things that you just enjoy, and never love and handle.
