There is a lot of sun in the late afternoon, so I could turn the heating pad down and they were still very warm and relaxed. And they’re visible to a camera with this lighting.
Every few tries at feeding, they eat well. I’ll probably try a little less often–say 3 hours daytime–and see if they like that better. They also like to be pretty warm. Matilda has pooped twice, Moose none yet, but I think he just has some catching up to do. He’s more robust and perhaps just more annoyed by the butt-wipes.
