Hi there, It's time to give my cat his insulin and I just opened the new bottle of Prozinc and it looks different from the last bottle. It was overall clear but with a large clump of thick white something on the bottom. I started to roll it in my hands and the clump got smaller and my insulin got cloudier. The clump is small now but not all gone. What should I do? Can I give my cat his insulin? Attached is the picture. I can't get a good shot of the clump. Thank you!
