I'm not sure where you are, but the cam is set live from Devon England, so you could go back when it's daytime there and you might see a bit more movement. Typically, the volume is turned on so you can hear the mom and kits (mainly the kits squeaking XD) . For the next week, there might not be too much movement seeing as the kits are still blind and the moms won't want to leave them for too long. However, in approximately a week once their eyes open... expect movement... a lot of it XD
The cam switches up between two litters. Sorcha (the pale one) and Cieara (the dark brown one). Eventually, it is very possible the breeder will merge the two litters together (once the kits' colors show up) seeing as the two moms are bonded (closer than sisters) and would enjoy each other's company/ability to help share the nursing and mothering duties.
