Hi Tunde - I live in Israel and we also use Novibic products here. I have been using Novibic Puppy DP for years with no problem, both for my private animals and the zoo's ferrets. Just follow the regular procedures and you should be fine. Feel free to contact me off list if you have any more questions, plus I have a great packet of information that the zoo allows me to send out under their sponsorship that might be of big help to your vet. It is in English. Take care, Bev from Jerusalem Beverly Burge Section Head - Hospital/Quarantine Medical Registrar Tisch Family Zoological Gardens in Jerusalem Fax: 972-2-642-1655 Phone: 972-2-675-0140 [Posted in FML issue 3241]
