Well, it wasn't unanimous at first. TC and LC dove right in, SK took a sniff, a tentative lick, then walked away.
So, while TC and LC lapped with enthusiasm I got out the trusty Vet's-Best, called SK back over, let her smell the V-B in my fingers, then dusted just a tiny tiny bit over the yolk. She tried the yolk again, decided it was good after all, then licked her dish clean, even to licking all along the rim of the dish!
In the meantime LC had finished hers and was looking for more. TC had left a small yellow puddle in her dish, so I gave her a bit of Vet's-Best too. I think that's why she left some, because she smelled the V-B and knew if she left something in her dish, she'd get some V-B. JTC has me well trained. Just to keep things fair, I gave LC some V-B too.
They each had about 1/3 of a yolk.
