With this heat, I had to move my guinea pigs from their usual cage in the lounge to the hallway, as it’s the only room in the flat without windows. I’ve been monitoring the temperature constantly with two thermometers—one in the cage and one in the flat. The flat has been sitting around 27.5–28°C.
One thing I’d recommend to anyone struggling to keep their pigs cool is freezing as many plastic water bottles as you can. I bought 24 cheap bottles of water from Asda, froze them all, and have been rotating them every 2.5–3 hours. I keep two frozen bottles in each pig house, and it’s brought the temperature inside their houses down to around 22–24°C. It’s given them some much-needed relief—and me some peace of mind too.
They don’t seem to like having the frozen bottles taking up space in their houses or beds, but I’d much rather they be slightly inconvenienced than overheating.
I’ve also been getting up every three hours through the night to swap the bottles over. I genuinely can’t wait for this heatwave to be over!
Another thing that’s worked really well is using slate table mats in the cage. They stay cool for much longer and seem to hold the cooling effect from the frozen bottles, giving the pigs another cool place to lie.
Wishing everyone the best of luck keeping their pigs comfortable in this horrible heat. Stay safe, everyone and don’t forget to keep yourselves cool too!
