I think the catcoin was mined yesterday. If its not handled automatically by tomorrow I'll look into it (might just be confirming still - takes a decent bit to dig in).
As for mintcoin, still holding out hope, the guy keeps posting that he's working on getting the stuck withdrawals fixed (ours is this). So maybe it will fix itself. I've been holding off removing them and writing it off for now, cause its going to be a bitch to remove and then re-add. For now, we'll wait about 1 more weke and then handle it.
I recall the catcoin being around for several days, but I could be remembering incorrectly.
Ahh, didn't keep up with the coinmarket happenings well enough. I thought the coins were just sitting on the exchange, not stuck pending withdrawal. Considering how much value the mintcoin has lost, I'd suggest the pool take it as a bonus and sit on it for a while (and earn some PoS rewards) to see if the price climbs again with the coin pure PoS.
