She has actually given me a bit of a reality check on how fragile life can be today. I think she may have a bit of a chill this morning due to last nights surprize 7C overnight (they live indoors but we're on nights and didn't know the temp was going to drop below 10C), and her ears were very cold.
She's much better this afternoon, and is tucking into her veg, i'm just going to have to keep a close eye on her for a few days, though she seems to have the ability to bounce back pretty quick from these dips. I just wasn't expecting one nearly three weeks since her last one. These piggies will be the death of me, laughs weakly.
On saying that, whilst she was tucking into some lettuce this morning ( was very relieved to find she had a good appetite!) she kept stopping and looking right at me, before eventually, jumping up to get under my blanket, there she stayed until I felt she was warm enough to go back with her siblings, I just gave her a warm beany wrapped in a blanket to sleep on (Truffles got more use out of it, she just seemed happy too cuddle up with Tilly in the house instead).
In 15+ years of guinea pig-keeping, only two have ever fallen asleep on me. The first one was Biscuit, on of my first piggies as an adult. I was lying on the sofa with Biscuit on my chest, it was a very warm and quiet evening. She had always been very trusting, and relaxed quite quickly. Next thing I know, she's nodded off with her chin resting on my jaw! Bless her! I couldn't move! The second one was Spirit, oddly one of the most nervous piggies I've known. He had got himself comfy in my lap one very quiet afternoon, slowly relaxed and eventually fell asleep. 
but Humbug my boy who does like to sit in the fleece on my knee never shuts his eyes, my new one Betsie is the one I am most weary of as she is feisty lively and hard to catch ,she has snuggled down on my knee twice stretching out and the eyes were closing , so cute !
