Track how food, nutrients, medications, and supplements affect your pet's health and weight.
HENRY helps you understand how food, medications, and supplements affect your pet's health and weight.
Whether your pet is managing a health condition, working toward a healthy weight, or you simply want to make more informed choices about their diet, HENRY gives you the tools to track, visualize, and act on the data that matters.
Inspired by Henry the cat with chronic kidney disease, HENRY has been built by pet parents for pet parents.
What you can do with HENRY:
• Log food, medications, and supplements quickly and easily
• Track calories and key nutrients against daily goals
• Set medication reminders and track doses with a built-in calendar
• Monitor weight and behavior over time
• Upload lab results and watch trends across visits
• See how nutrition, medications, and lab values relate to each other — in one place
• Discover your pet's top 5 foods
HENRY goes beyond a simple food diary. Detailed charts let you correlate lab results with nutrient intake, or see how medications affect appetite - patterns that are hard to spot with handwritten notes or even spreadsheets.
For pets with special needs: HENRY is especially valuable when your pet requires a carefully managed diet — whether due to kidney disease, diabetes, weight issues, or food sensitivities. Having all the data in one place makes vet visits more productive and day-to-day management less stressful.
Works on iPhone and web: Access HENRY on your iPhone or at henrypet.com. Your data syncs automatically.
HENRY supports cats and dogs, and multiple pets per account. It's free to use - no ads, no in-app purchases.
