I just started breeding my rats, and have been doing lots of research about different breeding setups. I know when you need thousands of rats breeding them is the only way so in some cases I guess the mason tubs are kind of needed for space reasons. But does anyone else find it inhumane for multiple rats living in a mason tub to be inhumane? I use big storage bins, not sure the qt size but its one of the biggest ones I could find, and I find them to be more "fair" in terms of living quarters. I think that fact that cant stand is what erks me. I just think there are better ways to keep rats other then mason tubs. Just curious to see how everyone feels on this one, and other breeding tub designs.
