I built a diy rodent tack for my breeder rats, and it worked great until tonight. I was tracking down the dead smell from some pups that had died in the rack ( I always get a few with the new mom rats). To my surprise I found an entire corner of the plastic tub chewed out ( which was not there when I checking in at lunch time for food and water bowels). The hole was large enough for the rat to fit the entire head and part the chest though. I was shocked. lucky me I still have a 40 gallon breeder tank to toss this batch in, on closer inspection it looks like the space between the top and the tub is enough to allow the rats to sart chewing on the tub ( found a smaller hole in another tub) I hope the foil tape will be enough to stop them tonight.
I am going to need to take the rack apart and cut the 2x2 down so they fit tighter in the center of each rack ( i built mine to hole 2 tubs side by side but I didn't think that the gap was that much.) lol so I going need to take the rack apart and rebuild it with 2x4 legs and shave about 1/4 inch off the center shelf lips to be tighter and make some wedges to hold the tubs tighter against the screen. and I figure that this would happen with the last of my asf not the rats.
