Amazon.com: OASIS #80069 Guinea Pig Vita-Drop Vitamins, 16-Ounce liquid multivitamin with Vitamin C : Health & Household

Great Value - Save lid from smaller bottle with flip up nozzle to avoid waist. The lid on this bottle is easy to over pour.

I have used many brands of many years. Vita-drops are all nutrients and no filler, no sugars, or no other additives

Clear instructions. Sturdy bottle. Just wished the cap was spill-proof, and that there was a conversion chart for multiple sizes of water bottles. Other than that, our boy seems to really enjoy his "flavored" water.
