So I have two tarantulas coming in, and two enclosures coming in. I knew I would be getting a third tarantula sometime in the next couple weeks so I would need an enclosure. So I was walking into my kitchen and my mom stops me. She was holding a really cool looking jar that used to hold coffee grounds. She asked if I could use it for one of my bugs, I immediately said yes. I took it and was thinking of what I could house in it. It was tall, wide at the bottom, narrow in the middle, and a little wider at top. (I'll give pics don't worry.) So I decided this would be cool for an arboreal sling (1 1/2" or under) or maybe even a terrestrial sling that likes deep substrate to burrow. I cut a hole in the top to stick some mesh in. The cut was kind of jagged so I sanded it down. I was looking for mesh but couldn't find any. I did find this drainage layer for plant pots that had larger holes than mesh, which allowed more airflow. And, it was pretty firm. So I cut it down to size, drilled so holes, and screwed it on. I still need to seal the edges of it to prevent escapees, so need to restock on hot glue sticks, am going to get some in half an hour. Here are the promised pictures. You can see my hair in one of them, didn't realize there was mirror there lol.
