For those that own spiders. Spiders are a wonderful tool. There are tons of questions on here asking "is my ball python stressed". Spiders are blessed or cursed depending on how you want to look at it with a built in stress indicator known as the wobble which specimens have to varying degrees. The demonstration of wobble symptoms is a strong indicator that the animal is worked up about something. There is good stress and bad stress. The animal could be hungry, uncomfortable, looking for love, afraid, etc. My spiders have taught me more about ball python husbandry and behaviors than all the other animals in my collection combined. If my spiders are not symptomatic odds are everything is right in their world. So, if you catch your spider acting out, take a minute and see if you can figure out what has gotten them excited. You will learn a lot.
