Welcome Becca and Kuzco, we need a bit more information to be able to guide you, I use ProZinc as well 1.25u every 12 hours, it sound like 5 units is a lot of insulin, also once you open a vial is good for 60 days, must be refrigerated at the same temperature, always, I will tag a ProZinc expert for you, also below there will be 2 links there will be instructions and what we need to get to know Kuzco more, also there's a food chart for you to choose from many brands, out diabetic babies must have a content of 0-10% carbs in foods, many of us member enjoy the variety of flavors that Fancy Feast Pates have also in US made, so no waste goes in their foods, dry foods and treats, contain a very high content of over 20-25% carbs, which beats the purpose of the insulin, also home testing is very important especially before every shot, the rule is test, feed, shoot, a great inexpensive glucometer is the ReliOn Premier monitor and strips, there are many stick notes in the Main Forum that will show help you along to get you and Kuzco on the right track , remember no concern is ever to small, we are here to help you
