I bought Octenisept for my cat that has long been a non-operable ulcer, which ignites again and foul smells. Now I have Octenisept used every two days and in addition Ringelblumensalbe. I can only say that the inflammation is gone and slowly closes. Very good preparation. I can only recommend. Since my cat has not been reluctant when I used it, I assume that it really does not burn.
