Built my first rack rack. Got the plans for south texas reptiles forum or something like that. Going to try the arb rat rack plans out next. Took me a while to build, but now that I know how to do it I'm sure my other racks will be built faster. I have a 1.7 in the tubs at the moment. I'm thinking its gonna end up being too crowded, but the breeder i got the rats from said it's ok. I don't know. I really do like the watering system though. It's very cool and helps me out by not replacing water bowls every hour haha. Can't wait to build some more.
