We had a recent hot spell. A hot spell in the northwest is 90's and no humidity. I realize people living in truly hot climates will laugh at that definition of a hot spell! But summers here are typically mid 70's with cool nights. We get the 3-4 days of 90's a summer and that's it.
The cats don't complain about the weather, they seem to prefer the cool over the hot, especially Nahum with his heavy fur coat. While enduring the recent hot temperatures they stretched out, lazed about and generally were disinterested in anything except sleep.
