Hi, My name is Els and I live in the Netherlands. I am a member of the Dutch forum for cats with diabetic. We have a lot of problems with the supplier of the syringes U100 by BD. We are looking for another company that makes good syringes and I saw some on: https://linteebean.com/2009/06/23/using-u-40-insulin-with-u-100-syringes/ Does any one know the company that makes the syringe with also the 0.25 marks ? Thanks in advance. Els.
