This is a 100% lie and literally anyone here with a single minute to spare could fact check and learn they aren't very intelligent at all. Nowhere remotely close to a dog or cat, and aren't even known to be the smartest types of spiders. It's kind of sad that 28 people straight just blindly up voted this comment without a single one of them knowing it wasn't true and didn't bother to check.
They're super cool, but they're still dumb.
