Sport the 5 signs

Here's what a cat who needs a spring reset actually looks like

Easy to miss or misread, these signs share the same cause: three months of indoor heating quietly depleted her hydration.

SIGN 01

She's still moving stiffly

Joint cartilage is 80% water. Three months of dehydration won't fix itself when the heating goes off.

SIGN 02

Dull coat or flaky skin

Coat health is last in line when the body rations moisture, so a dull coat means the deficit runs deeper than it looks.

SIGN 03

Less playful than before winter

If she's less interested in play than last autumn, that's not ageing, that's her body still running on low.

SIGN 04

Digestive changes that started in winter

Dehydration disrupts gut balance, and changes in appetite or digestion that appeared in winter mean her gut is still recovering.

SIGN 05

Drinking inconsistently

Cats' thirst drive is naturally weak — a cat not drinking properly can't recover from dehydration, no matter the season.

WHY HYDRATION IS THE RESET

All 5 signs have the same root cause 
— and the same fix

Plain Water

Plain Water

Water passes through without reaching joints, skin, or organs — leaving key cells depleted.

Electrolyte-Enhanced

Electrolyte-Enhanced

Electrolytes pull water directly into cells — reaching joints, gut, coat, and energy systems.

The Reset Formula

One sachet addresses all 5 signs

13 active ingredients. One complete daily reset.

Signs 1 + 3 — Joints + Energy

Rebuilds joints. Restores energy.

Stiffness and low energy come from dehydrated cells. Electrolytes drive water in, Glucosamine and Chondroitin rebuild the rest.

Signs 2 + 4 — Coat + Gut

Resets the gut. Restores the coat.

Coat and gut are last to recover from dehydration. Petralyte restores the moisture reserves both depend on.

Sign 5 — Drinking Habit

Even picky cats drink this.

A cat who won't drink properly can't recover. Salmon and tuna flavours rebuild the habit winter broke.

“No need to mask it—he actually likes it straight in his bowl. For a cat that usually turns his nose up at anything new, this was a huge win.”

“It blends easily and doesn't affect her appetite at all, which is saying something because she’s usually super sensitive to taste and texture changes.”

“She moves easier and plays more with her toys since we started using this. It’s been amazing to watch her regain some of her playful spirit.”
