Today one of my six month old silkies started rolling around and kicking her legs out making a deep kind of hole and she would lay in it and purr really loud then roll around again, kick out her legs to make the nest even deeper then purr again. Was she just dust bathing or is this a sort of nesting behavior? She hasn't laid yet and is not squatting yet.. The behavior kind of startled me at first until I realized she's either dust bathing or nesting. Which do you think it was? She would really get her legs going to make the area deep then roll around a little bit more and just purr and purr.. She even wallowed her head in the shavings. Which behavior does this sound like to you?
