It’s going to reach 40 Celsius here, and my house does not have AC
I’m really worried about my BP
what do I do to cool down his enclosure? He has a fully enclosed PVC cage, so any thing that I would use to cool off the cage has to be inside of the cage itself

ive heard of cold water bottles, but I’m worried about him curling up next to or on it and getting too cold ?
Any other tips or ideas?
