Thanks everyone! I had forgotten about stripping the bed and everything - what a pain! Plus definitely no sun to dry in at least until next week

I did cut her nails the other day as they were quite long so I will have to keep on top of that and get some more worm stuff to treat everyone. We don't use soap in the bath so it's not that and we use low irritant washing liquid so I'm fairly sure it isn't related to that. It does seem that it wakes her up around 9pm and she screams and writhes around in agony and it does seem to clear up with treatment so I am pretty sure it is worms.

I will do a follow up treatment and then do pre-emptive worming every month I think and see if that makes a difference. Off to strip the beds now GRRR!
