I wasnt sure if this goes here or in caging, since its a cage question, but for feeders Anyway.... we're about to set up 2 tanks of mice, and i was planning on building a wire cage thing kinda like the lids on the lab tubs that some people use to hold the food, and just hang in in the tank. My question is, would there be any problem with using copper wire to make it with. If you're not following what i mean let me know and i can do a drawing of what i have in mind, but mainly i just need to know if copper would be a problem.
