I have 3 racks for breeding rats. After a year of filling water bottles a couple times a day I decided it was time to hook up gravity water systems and make my life a lot easier. It really has made things so much better.

Now for the problem. I had several boxes of rats boxed up to sell and a few chewed out and escaped. I have sticky traps and snap traps with peanut butter just for mishaps like this. The traps have caught nothing and the loose rats are chewing holes in the tubing and flooding my tubs!!!

I need ideas on how to catch them as well as maybe a way to make the tubing chew proof. Any thoughts or ideas are greatly appreciated!
