I cleaned my tarantula cages on the weekend, switching from astro-turf to potting soil for substrate. I had them on astro-turf for the longest time but I don't think they liked it very much and soil just looks better. But the soil was moist and it steamed up their tanks, so I took the lids off a few to let the excess moisture evaporate. Well, the spider pictured below saw this as an opportunity to escape, bastard. Luckily she didn't go very far, just sat there on the carpet beside her cage. With a little gentle prodding [well not so gentle, the bitch clamped onto the carpet pretty good!] I got her into a scooper and back into her cage. Lids on tight, all the kids in bed. Goodnight!
