Now that you've used the new bins for a while, have you had any problems with rats escaping or any other problems? Have you altered the design any since making those? I want to try making some myself. Thanks!
I haven't had any escapees from those bins. They work wonderfully and as Jo said...there is plenty of air circulation which cuts way down on the amonia smell.
I believe I have a total of 8 of them now and they are all the same. No changes for me.
