Everything you need to know when choosing the right pet urn.
Humans have domesticated animals for thousands of years. As our pets become integral members of our families, it can be difficult to come to terms with their passing.
Many pet owners choose to memorialize their furry friends by purchasing an urn for their ashes. Whether it be a dog, cat, rabbit, or any other beloved pet, they deserve a final resting place that honors their memory.
Selecting a pet urn can often be overwhelming due to the numerous options available. Colors, shapes, materials—the choices are endless. However, one important factor that should not be overlooked is size.
This post will outline how urns are sized and provide guidance on choosing the appropriate pet cremation urn.
The Cubic Inches Method
One standard method to size urns is by the volume they can hold, measured in cubic inches. This measurement accounts for the density of the ashes, as heavier bones will take up more space.
To determine the appropriate size urn, start by calculating your pet's weight in pounds. Then, use the formula: 1 pound = 1 cubic inch of volume. If you need an urn for dog, you would consider the following:
A 20-pound dog would require a dog urn with a minimum volume of 20 cubic inches.
It is important to note that this is just a rough estimate, as the weight and volume of ashes can vary. It is always better to err on the larger side when choosing an urn, as you don't want to risk running out of space in the future. As a general rule of thumb, add an extra 10-20% to the calculated volume to ensure you have enough room.
What to do if you don't know your pet's weight
It is best to use a rough estimate if you do not know or remember your pet's exact weight. Alternatively, you can always choose an urn with a larger volume to be safe. Look for your pet's breed and average weight online, or ask your veterinarian for assistance.
Another option is to consider a keepsake urn, which is smaller in size and can hold a portion of the ashes. Keepsake urns are also often used as an extra resting place or memento, such as placing some of the ashes in a special location that holds significance for your pet.
Considerations for Multiple Pets
In some cases, you may choose to have multiple pets' ashes placed in the same urn. We call those companion urns. When selecting a companion urn, it is important to consider the total weight of both pets and follow the same calculation method outlined above.
For example, let's say you're shopping for a cat urn. If you have two cats weighing 10 pounds and 15 pounds, respectively, you will need an urn for cat with a minimum volume of 25 cubic inches. Add 10% for a recommended total volume of 27.5 cubic inches.
Final Thoughts on Pet Urns
Honoring the memory of a beloved pet is a personal decision, and selecting a cremation urn is just one small aspect of that process. Be sure to take your time and choose an urn that not only fits the physical remains but also reflects the unique spirit of your pet.
