The shelter has a lot of kittens coming, so they took Shadow and Umbra for neutering today and are keeping them. They had just wanted them with me to get them used to food. Instead, I mostly needed to get them used to people and each other. Umbra still has a bit of an issue about fighting her feet and Shadow is still shy, but they’re doing okay. I hope.
And I see by the shelter’s Availble Cats page, Shadow is now Shadowfax. So wrong for a shy grey kitten to be named after a fierce, blindingly white horse. I suppose they already had a “Shadow”.
