Oh no!! So sorry to hear of the death of two of your mice Kallan. I wouldn't have thought that the temperature has caused it though, I'm not too far from where you live and it doesn't seem to have affected my mice. Is it possibly their age? I hope that the rest of your mice are okay *hugs*

They were two separate lines, one siamese doe several months old, one pet shop broken tan male approaching a year.

I am getting ceramic tiles today, and little tubs to freeze water in, in case it was temperature.

Could you try the little freezer packs from Poundstretcher Extra or Asda? You can reuse them and they are only slightly bigger than a hand in size so you could leave them in the cage if you're concerned about the temperature
