Yikes! Hot weather = yuck, for mice. It was near 100F here today, but luckily I have 3 air-conditioning units.
Not sure how many people know this, but the reason heat affects mice so disastrously is because mice cannot sweat like people or pant like dogs, to cool off. A fan doesn't help mice because the way a fan works is to quickly cool and evaporate the sweat that comes off us. That's why mice need an ambient temperature of around 70F or lower to do their best. They can survive into the 70s for short periods of time but can't really take the heat for long periods or over and over.
I know a very prestigious show breeder who has won the best awards there are in the US, and whose mice were mostly wiped out a couple years ago because the air conditioner failed in 80 degree weather. It's really a tragedy whenever mice die due to heat.
