What is Cremation ?

Whilst we acknowledge that the majority of our clients already understand the details and process of cremation, this information is provided for those who would like to learn more about the topic. 

Cremation is the mechanical, thermal, or other dissolution process that reduces Pet remains to bone fragments.

Cremation also includes processing and pulverization of the bone fragments into pieces that are usually no more than one-eighth inch. 

PLEASE NOTE – With thanks, this information is credited to the CREMATION ASSOCIATION of NORTH AMERICA ( C.A.N.A ) which we are a Paid Supplier Member. 


We have taken the words HUMAN and substituted it for PET– as in Human Remains – now reads as Pet Remains etc.

The information that follows is intended to help the Veterinarian, Vet Clinics, Palliative Care Nurses, Grief Support Services and Grief Counsellors et.al. and to help assist their Clients ( the Pet Parents, Consumer / General Public ) to fully understand what occurs in the Cremation process.

The steps & information below was first written in reference to the Pet Cremation market- yet literally crosses over 99.9% into The Dog & Cat – COMPANION ANIMAL – PET CREMATION SERVICE Market & service procedures and offerings.

The comments and notices are detailed and should be carefully considered.

However, CANA offers- please note that this information has been prepared on a general basis.

Because of variations in Country – State- Provincial and Local laws, there may be some differences in legal requirements in different jurisdictions. Your chosen or any Pet Funeral / Pet Cremation Service Provider should be able to explain legal requirements in your area.

Types of Cremations

This definition covers a variety of technologies that may be used in order to achieve reduction to bone fragments, including traditional flame-based cremation and Alkaline Hydrolysis.

Flame-based Cremation

Gas Fired-Flame-based cremation uses flame and heat to reduce the Pet remains to bone fragments, or cremated remains. This is completed within a machine called a cremator.

Flame-based cremation is the most common type of cremation, and is available through most funeral homes, crematories, or cemeteries. This process is detailed on this page below.


Alkaline Hydrolysis

Alkaline Hydrolysis reduces Pet remains to bone fragments, cremated remains, or more specifically hydrolyzed remains, through a water-based dissolution process which uses alkaline chemicals, heat, agitation, and pressure to accelerate natural decomposition.

Alkaline Hydrolysis is a newer technology, and is currently only available in a few states and provinces in the U.S. and Canada. Where alkaline hydrolysis is accepted, there are limited providers available. For details on this process, visit our Alkaline Hydrolysis page.

Flame-based cremation and alkaline hydrolysis are the legal cremation processes in the US and Canada at this time. Additional processes may be in development but not currently accepted by the regulators.

Essential Elements of Cremation

When comparing prices and providers, ensure each element below is included in the quoted price.

Ask questions about the company’s procedures for changing of identification from the point of removal on, to ensure that the deceased’s identity is carefully confirmed.

You may choose to have visitation or viewing prior to cremation, possibly involving embalming, setting features, and washing or dressing the deceased. You may also arrange to witness the cremation itself.

When comparing prices and providers, ensure each element is included in the price and ask questions about the specific policies and procedures for chain of identification at each step.

You may still choose to have a visitation or viewing prior to cremation, which may involve embalming, setting features or washing and dressing the deceased. You may also arrange to witness the cremation itself.


The deceased will be removed from the place of death and taken to a funeral home; on rare occasions they may be taken directly to the crematory. From the point of removal on, the deceased’s identity is carefully confirmed at each step in the process. This ensures that a chain of identification is firmly established.


It takes time to finalize the paperwork and make plans, so until the services are planned and the cremation is scheduled, the deceased will be placed in secure, cold storage.

The time between death and cremation can vary considerably based on many factors; cremation typically occurs at least 48 hours after death.

Steps in the Cremation Process

  1. The deceased Pet 99% of the time will be placed in a simple low-cost cremation container made of cardboard etc. The minimum requirement for a cremation container is that it be completely enclosed, rigid, leak resistant, and combustible. You may select a cardboard or particle board container or a wooden casket provided it is combustible and non-toxic.
  2. NO metal caskets etc can be cremated.
  3. Facility staff will confirm the identity of the deceased by checking all paperwork. A cremation number or other identification (id) will be assigned. This number/id is often stamped onto a stainless steel disc, but may also be in the form of a barcode. The id/number is recorded on a cremation log. The stainless disc remains with the remains throughout their entire time at the cremation facility.
  4. When it is time for the cremation of the deceased Pet, they will be removed from the storage unit and their identification will be confirmed using paperwork and the stainless disc. The container will be taken to the cremator unit and placed on a table in front of the cremator door.
  5. The door of the cremator will be opened, and the container will be placed inside the primary chamber. Usually this is performed manually with the aid of cardboard rollers or mechanically with a rolling conveyor loader. The stainless disc with number/id will be placed inside the cremator with the Pet remains.
  6. The door will be closed and the cremation monitored carefully until it is completed. The process can take anywhere from 30 minutes up to 120 Minutes / Two hours depending on the body size and stored heat in the chamber.
  7. When the cremation process is complete, the door will be opened and identification checked again against paperwork and the stainless disc. The bone fragments that remain, now called cremated remains, will be carefully swept out of the cremator into a cooling tray, allowed to cool and taken to a processor
  8. The processor is a machine that uses blades to pulverize the bone fragments until the remains are less than 1/8” in size.
  9. The cremated remains are then transferred to a strong plastic bag and placed in either an urn or temporary container if the family has not selected an urn yet. Identification is checked again and the stainless disc is placed in the container with the remains. The urn and its box are labelled with identifying paperwork and checked again before being stored for the family’s retrieval.

The Technical Details

The process of cremation is essentially the conversion of a solid to a gas. This is accomplished by heating the body, which contains between 65% and 85% water by weight, to a temperature high enough to facilitate the combustion process. Laws for required temperatures vary by state, but the cremation process usually occurs between 1400 and 1600 degrees F.

The combustion process in the cremator proceeds in two stages — first is primary combustion of the deceased in the main chamber of the cremator. Tissue, organs, body fat, container materials burn off as gases and move to a secondary chamber, where they continue to undergo combustion.

The bone fragments remain in the primary chamber. The inorganic particles, usually from the cremation container, settle on the floor of the secondary chamber.  The gases formed as a by-product of combustion such as carbon dioxide, water, oxygen, etc. finally discharge through a stack in the roof of the crematory building.

What can be Cremated?

Items of the deceased Pet such as collars, bells etc. or other items will be removed from the container and returned to the family with prior arrangement. Sometimes families request that items of significance be cremated with the deceased Pet – things such as their favourite Toy, Blanket etc. In some cases this can be allowed, but in many cases it cannot.

This is for safety reasons, as not everything is combustible and may cause damage to the equipment or the operator if left in the container. The Pet Funeral Director- Cremation Service Provider will advise the family on what can or cannot be put in the container with your beloved Fur Baby.

What is in the Cremated remains?

The bone fragments that remain in the primary chamber are mostly calcium phosphates, with some other minor minerals. Cremated remains are generally white to gray in color. Additionally, there may be little pieces of metal in the cremated remains – this metal may come from surgical implants etc or a collar with a name tag etc that was not removed prior to cremation. The metal is separated from the cremated remains before they are processed (pulverized). The metal is typically recycled or given back if asked

The average weight of Pet cremated remains is well under 1 pound; a tiny percentage of the Pets body / original mass. The cremation chamber is either swept thoroughly or vacuumed with specially designed equipment to retrieve as much of the remains as possible.

How do I know I am getting my pets Remains Back?

Chain of custody refers to the chronological documentation of the custody, control, transfer, analysis, and disposition of remains and personal property. This is an important definition. Cremation is an irreversible, unstoppable process.  

Every step of the process needs to be documented, from the receiving of the Pets remains to the ultimate disposition of the cremated remains, including returning the cremated remains to the authorized agent- Veterinarian or Client direct if planned that way.

Identification Checklist :-

  1. Removal of deceased Pet from place of death
  2. Transport to crematory by the Owner or the Cremation Service Provider
  3. Placement in storage if needed
  4. Placement in cremator
  5. Removal from cremator
  6. Processing at pulverizer
  7. Placement in urn of choice as purchased or into a temporary Container supplied FREE of Charge
  8. Return to authorized agent Veterinarian or Client direct if planned that way

It is important to note that each Country, State, Province and Local Government requires different operational data to be recorded, and requires specific forms of documentation, thus each facility may have different policies and procedures which will vary slightly from the above.

The Pet funeral director / Pet Cremation Service Provider can advise the family of what their facility’s procedures are and what to expect.
