Since about 2 1/2 years I have a dirty cat lady (with 3 males). I have operated causal research without end, but also with the help of a friendly breeder and my vet I could not find the root of evil. By a lucky chance I came across the HP a Main Coon breeder to BIODOR. She wrote about the means that it even helps if your breed cat had again used perfume brand "Boss" by the smell really removed and not just glossed over. - That was for me a hint: perhaps it smelled my Lady so in the truest sense of the word when the "village" smelled excessively after hangover !!! Long story short, I ordered the medium and it used both playing air guitar and while cleaning the Katenklos, and I believe it himself barely, but in the past 4 weeks nothing has gone wrong. That is, as I said, since 2 1/2 years not happen! I think those who are affected by this plague, know how happy I am! I'm going to buy more resources again !!!
