Insulin Syringe U-40 1 cc 28gax1/2" 100/Box is recommended for use with Vetsulin insulin or PZI Vet cat insulin (U-40) to help treat pets with diabetes. This syringe is specifically designed for use with pets, and because U-40 insulin is weaker than U-100 insulin, it allows for larger, more easily measured doses.
