So it is down to two of the suggestions, although they were all pretty good! Some to keep in mind for the future (the very distant future!).
I think it will either be Iffie (adjusted spelling to diassociate from Big Brother contestants) or Grace as I love the idea of her being sort of linked to one of my favourite boys, Memphis.
I think she slept snuggled into me and Dave on the bed last night as I woke up boiling to be stared back at by her sitting right next to my face! I adjusted the covers and when I looked back she'd gone but Dave was still asleep very close to where she'd been
Now this morning she stood on my tummy/chest and padded and purred away, first time she's actually got on me. Now she's snuggled into my legs in bed, Dave on the other side
Even better is that Chilli didn't hiss at Dave for the first time in a while when he touched noses with her
Things seem to be settling down nicely
