Yes, I believe you should stock some Critical Care because if you should ever need it, you'll have it on hand and not be scrambling to get some. I bought my Critical Care from Menegerie here on CnH. Critical Care is used when a chinnie is sick and not eating and needs to have some nutritious food syringe fed to them to keep their digestive tract in good health. I store my unopened Critical Care in the freezer. Here is the link to where you can buy some Critical Care.
