I have one kitten (approx 6 mo old) that I rescued recently. We live in a small place (approx 700 square feet) and are renting. We hadn't planned to get any cats/kittens until we got our own home, but Obi found us not the other way around! Anyway, we don't intend to try for a home for another 2 or 3 years. So we'll remain in this place until then (low rent, so we can save up). Given this small space, how many cats is too many? Both my mother (who calls Obi her grandkitten) and my husband think Obi should have a sibling to play with. I'm a bit concerned that we don't have room for a second cat. So, advice? What is best for Obi? Should we find a sibling who needs a home, or let him remain an only child for a few years until we get more space?
