Early is cheaper

Keeping your cat healthy shouldn’t be expensive.

52% of US pet owners have skipped or declined recommended vet care. 71% of them cite cost.

PetSmart Charities and Gallup, 2025

We hope Pelle helps you notice things early, so the next vet visit can be a planned one at a price you expected.

Pelle

About the size of your fingertip,
twenty millimetres across.

A little matte silicone node rests softly in front of her ear.

Fresh every night

Stickers don’t stay on fur for long, so you pop on a fresh one each night. We send you thirty a month, so you won’t run short.

Nothing to catch on

The charms are moulded right into the face, under a millimetre high, so there’s nothing for a paw to catch on.

What’s inside

There’s one small board with a coin cell behind a screw door, and a hydrogel sticker underneath that holds it all on. The sticker is the only part you ever replace.

Pelle App

Your cat can’t say where it hurts,
so we help them tell you.

Pelle gently turns all of it into two things you can read at a glance.

1. Measured against their own usual

Pelle learns what’s normal for your cat, so any change is measured against them. A note like “quieter than usual today” is easy to read and easy to share with your vet.

2. Your cat, in their own words

A little avatar that shows how they’re doing, and a sweet note from them whenever you’d like one.
