I've been thinking about giving my hermies canned vegies here lately, but I'm unsure about the vegies safety. A lot of the vegies I buy are salt free, so the only ingredients are like green beans and water. However, I'm not sure that the vegies haven't taken on some of the metals from the cans. Does anyone know if this is true or if this will hurt my hermies? I tried to search this on this site but I didn't really find anything. Any ideas would be appreciated!!!
