One Piece - Collars

Yes, our cat collars have breakaway buckles.These “safety” or “quick release” buckles are designed to release under pressure if your cat gets caught, keeping them safe from harm.

Yes! All the collars we sell are fully adjustable, making it easy to find the perfect fit for your pet.

Adjusting your collar is simple, but if you need guidance, we’ve got you covered! Check out our step-by-step Collar Adjusting Video for a quick and easy tutorial.

No, we chose to use leather for pet safety.

Leather is flexible and lightweight, making it safe for pets. Lightweight metals can have sharp edges that might harm them, while smoother, heavier metals are less suitable, especially for cats.

We love hearing your ideas! While we don’t offer fully custom designs, we’re always open to suggestions for future collections.

Each collar comes with the buckle suited to its type: a safety breakaway buckle on cat collars and a secure side-release buckle on dog collars.

All of our plastic buckles are made of polyoxymethylene (POM).

POM (Polyoxymethylene), also known as Acetal or Delrin, is a high-performance engineering thermoplastic- a formaldehyde-based engineering plastic. It is specifically designed to bridge the gap between ordinary plastics and metals.

Did You Know? POM is often called "Plastic Steel" because its molecular structure allows it to behave more like a metal than a traditional plastic, providing incredible fatigue resistance for parts that need to open and close thousands of times.

We are currently unable to offer metal buckle alternatives.

Dog collars have a secure, non-breakaway buckle and a D-ring, so you can attach a leash.

Cat collars use a breakaway buckle for safety — it's designed to pop open under pressure so your cat can free themselves if snagged. For that reason a cat collar should not be used with a leash. To walk a cat on a leash, use a harness instead.

Collars are sold on their own — a leash isn't included. Many designs have a matching leash available separately, and our leashes use a universal clip that pairs with our collars and harnesses, so you can mix and match. Browse the matching design or our Leashes collection to add one.

Spot clean your collar with mild soap and cold water, then let it air dry.

We don't recommend machine washing or tumble drying — the designs are sublimation-printed, and harsh cycles or heat can affect the print and hardware.

Use a flexible measuring tape or a piece of string* around the pet’s neck. Allow room by placing two fingers between the collar and the pet’s neck. 

*When using the string method, a flat ruler is needed to get the measurement after getting the size around the pet’s neck.

Cats' natural behaviors like scratching, climbing, and chewing can cause collar wear and tear. To prevent this, regularly check and maintain the collar, and use treats to help your cat adjust. If your cat shows discomfort, remove the collar and reintroduce it gradually. For more tips, watch instructional videos on training cats to wear collars comfortably.

• One size: 8-12" (One size fits most)

Dog Collars:

• Extra-Small: 8-12"
• Small: 10-15"
• Medium: 13-20"
• Large: 16-26"

Although we always recommend measuring your pet's neck size, you can use the following as a starting reference point for sizing:

Cat Collars: Fit cats from 6 lbs to 22 lbs

Extra-Small (≤12”): Dogs up to 10 lbs

Small (11”-15”): Dogs 11-25 lbs

Medium (13”-18”): Dogs 26-55 lbs

Large (16”-24”): Dogs 56-80 lbs

Cat collars come with a bell attached to the collar with a split ring. The bell and split ring are removable. The buckle is a breakaway.

The x-small dog collar comes with a D-ring for leash and tag use. The buckle is NOT a breakaway.
