Ace and Pup are doing well. Ace is scarfing down piles of worms. This afternoon I took a peek into the tent and saw, in amongst the folds of hanging cloth, Ace with a tiny shadow crawling around her head.
The problem is the release. I have to let her go in a way that keeps her happy and with the pup. I think I'll cut a lump of tent-cloth out - the bit where she had the pup - and fasten it into a release box. Hopefully it will keep her happy enough.
I'll have to ring She Who Knows, in Sydney.
