@catsalad We live in a very active earthquake zone. 3 major ( >6.5) quakes in the last 4 years. Earthquakes were fun until we went through the Loma Prieta quake in the Bay area in 1989. Quakes up to 5 are ok. After that the can be scary depending on how close you are and what type of building your are in. Cats don't like earthquakes at all. Ours have issues from all the ones we have here in Ferndale.
