I agree with aart. Take the food & water out of the tray and separate it a little. Give them more room to access it. Another thing you can do is sprinkle a bit of their food on the paper towels. This will give them an idea of what their food is.
All snug in their bed. Let me know if I've missed something. I was right to be worried about the gaps in the wire. Even though I put some mesh up one still got it's head through. If I didn't have that mesh they would be able to get out and they're curious little things. I've since moved the mesh over so the gaps are even smaller. They seem happy for now but I'll keep checking them just to make sure. They came out for a little exploration and most of them couldn't find their way back
They look like they really like their mhp. They look so cute all cuddled up underneath it.
