Oh my! That's a very fancy box! The ones I have are carved wood, both the same although years apart. From one box I scattered some of the ashes on the former owner's grave and then some on the companion cat's grave. From the second box I scattered some out in the yard, for that cat was semi-feral and I knew he'd be freaked to be indoors all the time.
Crazy. But comforting.
Hope having MowMow at home is a comfort to you. Geez, just writing about the ashes has made me cry *again*. Sigh.
