Their teeth and nails are growing fast (their nails have been trimmed twice already). This is all much to the chagrin of Sarah, who remains stoic despite her tender teats, albeit a bit less patient with long-term feedings.
Here are current pictures of the little ones. Cobalt is the "cow dog." Tess (the only female) is the only dark brindle. There are two lighter brindle boys, Nickel ("Nick") and Charcoal ("Coal"). Coal has a black collar, but Nick's collar has fallen off. Nick has a small white tip on his tail. There are two solid fawn-to-blue (Maybe blue-fawns? We'll see as they grow older): Indigo ("Indi," who may have a purple collar on) and Slate ("Sluggo"). Slate was the runt, so he's a bit smaller, and he is a bit lighter in color and has a distinctively dark muzzle and ears. Indi is a little darker, with a lighter face and a white tip on his tail.
