Dude spiders are the chillest critter to have in your place I've been singing their praises for awhile.
Yea, my only ground rules are no hanging out around the toilet and stay out of the kitchen.
My current place actually has a few Gecko's living in it. I keep putting them back outside but they get back in. The ones on the front stoop are frickin' huge this year though. They've been feasting.
