Are we missing a cat or dog breed on our weight list? Please contact us and we’ll add them to our list. If we are missing an important volumetric measurement such as pints or other, please let us know.
We would appreciate any crematoriums who would be willing help us craft a better cremains calculation. If we can get a couple crematoriums in the pet cremation industry to submit their personal calculations, we can average those “weight to cubic inch” calculations and provide a more helpful tool.
We hope this page is a useful resource, let’s make it even better!
