Anicura

Hi! Has anyone tried anicura on cats who overgroom? I’ve read it has tea tree oil, lavender and aloe Vera in, all of which are toxic to cats - so why are they selling it and people claiming it is a miracle cure? We have tried everything with our rescue Siberian, if you seen my other posts you’ll know! Currently trialling nutripaws anti itch treats again, still not convinced they will help though.
