Your dog or cat was family. Choosing their urn should not add stress to an already painful moment. This guide helps you find the right size in one minute, using your pet’s weight, and shows exactly what you receive, how the urn works and what it costs.
Tree Urn is a biodegradable cork urn with two compartments: the ashes rest in the lower one, and a young tree or plant grows in the upper one. Buried in your garden or in a pet cemetery, it turns your companion’s memory into a living tree.
Which urn size for my pet? Weight, capacity and price
Three sizes cover every companion, from a hamster to a giant breed dog. Find your pet’s weight in the table, and you have your urn.
| Pet’s weight | Urn | Ash capacity | Price | |
|---|---|---|---|---|
| up to 10 kg / 22 lbs | Size S | 0.40 L / 14 oz | 79 € | Choose S |
| up to 45 kg / 100 lbs | Size M | 1.60 L / 56 oz | 169 € | Choose M |
| up to 90 kg / 200 lbs | Size L | 3.20 L / 112 oz | 269 € | Choose L |
A simple rule to check: weight in kg × 0.035 = litres of ashes. A 20 kg dog leaves about 0.70 L of ashes, so Size M is the right choice.
If your pet is close to the limit of a size, choose the larger one. Your crematorium can also tell you the exact volume of ashes collected.
Why weight is only a guide
Cremation ashes come mainly from the minerals in the bones. Fat and soft tissue burn away almost entirely, so an overweight animal does not necessarily leave more ashes than a lean one of the same size. Age, health and sex also play a role, with differences of up to around 20%. The capacities above leave a comfortable margin for these variations.
Quick guide by animal and breed
Breeds vary, and every animal is different: always check your own pet’s weight. As a starting point:
- Size S: cats, rabbits, guinea pigs, ferrets, and small dogs such as the Chihuahua, Yorkshire Terrier, Jack Russell, Shih Tzu or Dachshund.
- Size M: medium and large dogs such as the Beagle, Cocker Spaniel, Border Collie, Labrador, Golden Retriever, Boxer or most German Shepherds.
- Size L: giant breeds and heavy dogs such as the Great Dane, Newfoundland, Saint Bernard, Leonberger, Mastiff or a large male Rottweiler.

What is included with every urn
- The cork urn itself, made of cork powder, cork granules and a biodegradable binder.
- The Regulator, the cork piece that separates the ashes from the roots at burial.
- A printed personal message on the urn, free of charge: a name, dates or a few words.
- Gift packaging: a green foldable box for Size S, a green and gold box for Sizes M and L.
- Delivery worldwide where FedEx operates, in Standard or Express.
The tree or plant is not included: you choose it yourself at a local nursery, so it suits your climate and your garden.
How it works, in four steps
- Place your pet’s ashes in the lower compartment.
- Place the Regulator on top, to keep the ashes separate from the soil and roots.
- Plant a young tree or plant from a nursery in the upper compartment, with soil.
- Bury the urn in your garden, a pet cemetery or any place where it is permitted.
Over time, the roots grow through the cork and gradually reach the ashes, while the urn decomposes naturally in 6 to 8 years. Our step-by-step planting guide explains each stage in detail.
Why a young tree and not seeds? Cremation ashes are highly alkaline, and seeds placed directly on them rarely germinate. A young tree, kept apart from the ashes by the Regulator, has the strength to grow first and to reach the ashes gradually. Read why we chose a young tree.
A free printed message for your companion
Every urn can carry a personal message, printed free of charge when you order: your pet’s name, their dates, or a short phrase that captures who they were.
For children, this gesture matters. Seeing their companion’s name on the urn and helping to plant the tree gives a concrete form to the farewell, and a place to return to as the tree grows. Our personalized dog urn and personalized cat urn pages show examples.
Where can you bury the urn?
Your own garden is the most intimate choice: your companion stays close, under a tree you can watch grow through the seasons. Pet cemeteries offer a quiet, dedicated place if you have no garden or prefer a separate place of remembrance.
Rules differ from one country to another. Before burying, check our guide Can I bury my pet’s ashes in the garden?
