Here ia a pic of a couple of mouse racks, the first one on the left is the old style (version 1) and the one on the right is the newest design (version 3).




This pic shows the tubs hanging on the newer style racks.




This pic shows the track the tubs slide in.




The food trough on these new racks can hold up to 3-4 weeks worth of food, but I usually only fill half way. I just ordered auto-watering valves to run to the tubs. I have a total of 90 tubs of 1.5 mice in this room. 12 tubs of version 1, 24 tubs of version 2 and 54 of version 3. I will convert all to the newer version. These have ease of construction, easy access to fill food hoppers and visibilty into the tubs.

Like they say "practice makes perfect".
