Well Jo the vet had a good look at madam's toe and really felt that apart from the joint being a little enlarged and the area being red that it was nothing to worry about. Comparing the toes on both of Lucy's feet, she does have large joints and that added to the fact the she's been licking one makes sense to me.
She had an area which looked like a small wound which was a little gunky yesterday and I've kept it clean (as much as I can

) and bathed in CS.
Basically Jo is not concerned but said to ring if it changed for the worse over the next couple of days.
Maybe (for once) I was being a worrier

but as it was the same toe as her previous problem I wanted to get it checked.
Lucy was delighted to see Jo who gave her a biscuit and a cuddle and didn't charge for the consultation.
Thanks for all your support,
Val and, of course, Lucy
