Sage thinks it is weaning time but they are too young. Silly Sage. They tried and tried upstairs to feed but she was growling a correction at them saying the milk bar is closed. She did feed them downstairs.
She can't wean them till they are eating food well enough and drinking water sufficiently.
Here is the gallery from 1st time upstairs with both litters.
I assume you can tell the difference now between each litter.
