Absolutely not. I made a moc scrape more than 2 weeks ago and its tore to high heck every night. Dont over do it though on the urine. Make sure you place the scraper under a low over hanging branch that is about 4-5 feet high. Sprinkle that buck urine around on any lower lying vegitation as well around the scrape. Give it a day or two and theyll have it tore up. Remember more than one buck my visit the scrape.
