Glad they're ok!
Don;t beat yourself up over it you;re doing a marvellous job with them.
Winston hates being shampooed, he moans and groans all the time, it is a military operation so I sympathise with you.
As I said previously my 2 have got lice at the moment, Winston's had them on and off for a few months and I;ve been shampooing him with lice n easy. When we got Beanie Beth at Brinsley animal rescue mentioned piggy potions book by peter Gurney and to use the aromatherapy option. so i;m trying that at the moment. If they need more treatment so be it but it seems to be doing the trick. They both love burying themselves in the hay too.
keep up the good work, you're doing really well and they're 3 lovely piggies who appreciate you very much
