After the hiss last night I decided to leave the door off the dog crate to see if maybe mama moo needed to be away from the babies for a bit and too see what she would do. I have her in a room that has a desk in front of the window so she gets some sunlight and with full run of the room she can look out and get a break from the babies. The room is the warmest in my house and fairly small. I moved her litter box and food bowls out of the crate but close enough for her to see them from inside the crate. I thought she would move the babies from the crate in the night but this morning they were still in there and she was with them - right in the middle of it. I put her wet food out and fresened her water and dry food and cleaned her box. She did let me pet her and the babies with no thoughts of moving.
Seems things are going well.
