I caved and bought an air conditioner on Saturday and I'm embarrassed for my reasoning. My cat.
The past few weeks, Mushi has really been struggling with the heat. We've been doing all we can to keep him cool and hydrated (extra water in his food, rubbing him down with cool water around the neck and laying him in front of the fan). Unfortunately his health weakened and he developed quick shallow breathing, panting, fever and unintentionally playing dead. I felt bad for the little guy, it's his first summer and he has a much denser coat than Nami. Nami has also been laying around feeling the heat, but her energy levels are much better. She also has a few summers under her belt and her coat is finer.
With the weather reaching 49C with the humidity last week, it was a little too much for even Robert and I. I've never owned an air conditioner and felt that not having one made me stronger. After purchasing a behemoth portable a/c, it makes this particularly hot summer so much more tolerable.
After 12 hours of running the a/c, Mushi was back to normal. His breathing is steady and he's running around causing trouble like a cat should.
