In loco parentis

Our son and family have gone away for a week and we are looking after their cat, which is pretty easy , we know what we’re doing with her, and his chilli seedlings which is an awesome responsibility.
They are thriving and growing well ( The chilli seedlings that is) and in one of the pots this little fungus has popped up. 
Tiny Tuesday theme is circles . This is circular when viewed from on top, but  you’ll just have to imagine that.
