Cremation remains have no odor. During the cremation process the flesh of the body is burned away, leaving nothing but bones, buckles, and dirt. Most animals have little scent even before cremation. The only way an animal would smell prior to cremation is if the owner and/or worker brought the pet to the facility with an odor. The temperature of the furnace can range from 1800-2000 degrees Fahrenheit, which causes the flesh of the body to burn away.
