Thank you! As it turns out, I had a newer tube of it in the cabinet that I had forgotten I bought "just in case." I'll hold onto the older tube as a back-up, but used the newer product today. Thanks again.
Previous guinea pigs were given Terramycin. On another forum I was told Terramycin can kill guinea pigs and that I was lucky I didn't lose my babies. So which version is true? My girls got their Terramycin via injection. I would like to know as for many years I have feared Terramycin being used on my babies again.
