I'm not great with measurements, so if i had a 1 ml syringe, how much of this would i use for an adult cat?
Answer by • Nov 02, 2017
For cats over 6 months you'll administer 1.25 milliliters (¼ of a teaspoon) which contains approximately 250 milligrams of L-Lysine. The suggested administration for kittens under 6 months of age is 0.65 milliliters (⅛ of a teaspoon). The doses will be administered twice daily unless specified otherwise by a veterinarian.
