I don’t know if it can really be prevented with dyed items. It’ll always run in boiling water I would’ve thought. Although for future reference I certainly wouldn’t reuse any wooden chews, houses, wheels, and anything else that has been chewed or heavily peed on. Not at all convinced boiling them makes them good as new. I wouldn’t reuse wood with any rough surfaces either. The smoother ones like grapevine or plywood items are easier to clean so that type might be okay.
