Formula reviewed by veterinary nutritionists
"Most cat owners don't realize how little their cat actually drinks. A daily lickable supplement with prey-level moisture and this ingredient profile is exactly what I recommend for indoor cats. It's practical, palatable, and addresses hydration at the root."— Dr. Sarah Mitchell, DVM Veterinary Nutrition Consultant, SuperCat

Daily usage for optimal results
One sachet per day. Tear, squeeze, and let her lick. No mixing. No hiding in food. No negotiating.
| Weight | Daily Amount |
|---|---|
| Under 8 lbs | ½ sachet per day |
| 8–15 lbs | 1 sachet per day |
| Over 15 lbs | 1–1.5 sachets per day |
💡 Pro tip: Serve at room temperature for maximum palatability. Most cats prefer the sachet squeezed onto a small plate or licked directly from the pouch. Store unused sachets in a cool, dry place.

Frequently asked questions
How is this different from wet food?
HydraFlow delivers 84% moisture plus five clearly listed actives: D-Mannose, N-Acetyl-D-Glucosamine, Taurine, FOS/Inulin Prebiotic, and L-Theanine.
What if my cat won't eat it?
The sachet uses bonito and chicken liver flavors. In palatability testing, nine out of ten cats consumed the full sachet. If yours doesn't, our 90-day guarantee covers you completely.
Can I use this with prescription urinary food?
SuperCat is a nutritional supplement, not a medication. It's designed to complement — not replace — your vet's recommendations. We always encourage sharing supplement details with your vet.
How many calories per sachet?
Under 14 kcal. Designed for convenient daily use as part of your cat's complete feeding plan.
Is this safe for cats with kidney disease?
SuperCat supports healthy hydration, a core recommendation for kidney health. Cats with diagnosed CKD should have their supplement stack reviewed by their vet. The mineral profile is intentionally low.
When will I see results?
Most cat parents notice reduced bowl-drinking in the first week and larger, more dilute litter box clumps within 2–4 weeks of consistent daily use.
How does the subscription work?
Choose your supply. We ship automatically so you never run out. Adjust, pause, or cancel anytime online. No commitments, no fees, no hoops.
What's your return policy?
90-day money-back guarantee. If she doesn't love it or you don't see a difference, we refund every penny. No questions asked.
