I was just going to say that, boy, did you pick the wrong forum to ask that, since most of us are incorrigible, and are always cheering for another addition, but then I saw the reply above, so never mind! LOL.
It really does depend on your individual situation, and how tolerant your cats would be to a newcomer. It may work out, or they may hate each other's guts. But one excellent point to put into the pro-addition column is that you're moving to a new place. No one's put territorial dibs anywhere yet, so an addition may not be as traumatic.
How exciting to move to a new (bigger) place! Planned enclosure, even better!
