I actually have the heating pad on, but at the lowest setting. The house does not reach the recommended 80 deg F, and they still hang out and sleep on the heating pad. Generally the greys spill out, with only an occasional twitch to show they’re still alive.
They’re getting less shy. I brushed Juniper while brushing my hair and he loves it, I got out the little kitten brush and he even offered his belly for brushing. He’s been very shy about his belly.
They’re all gaining weight nicely, scampering about, and even chasing balls. I think they’re 4 weeks old now.
