Both.
I grew up with more cats though. I like how low maintenance they are.
EDIT: With the caveat that I live in a rural area and our cats were outdoor/indoor cats, so they spent a lot of time outside when they needed to burn off some energy, and they were housebroken, etc. A lot of cats are fairly okay with moderate to low levels of attention and ours were quite happy with cat napping most of the time.
