Cellar spider question
One of the many cellar spiders that live in my house was making very strange movements in this upside down position - looked like it was handling a very small piece of food'woth all its legs (no food present) Does anyone know if this is good or bad news? I thought it maybe shedding as I've found old skins in this exact shape. Thank you for any help (Apologies for poor photo I only have a cheap phone) .
