What Is Pet Cremation? A Guide for Families in LA

Pet cremation is the process of gently reducing a body to its mineral remains — the soft, ash-like material that families take home in an urn. It's the most common aftercare choice for pet families in California, partly because backyard burial is restricted in most LA neighborhoods, and partly because it gives families something physical to keep, scatter, or bury later when the time feels right.

But "cremation" isn't one thing. There are two methods used today: flame-based cremation, which most people picture when they hear the word, and water-based cremation (also called aquamation or alkaline hydrolysis). They produce a similar result — clean, soft remains — but the process, the energy use, and the experience are quite different.

The two types of pet cremation

Flame cremation

Flame cremation uses a gas-fired chamber heated to roughly 1,400–1,800°F. Over two to three hours, the body is reduced to bone fragments, which are then processed into ash. It has been the standard for over a century. It works, it's well understood, and most LA-area cremation providers still use it. The trade-offs are environmental — significant natural gas use, carbon emissions, and mercury release if the animal had certain dental work — and experiential, since "fire" is a word some families find hard to sit with.

Water-based cremation (aquamation)

Water-based cremation uses warm water and a small amount of alkali — the same chemistry already present in soil — to gently accelerate the natural process of returning to the earth. Over 6–8 hours in a stainless steel vessel, soft tissue dissolves completely, leaving only the mineral bone structure, which is then processed into a fine, silky ash. There is no fire, no smoke, and no emissions. It uses about 90% less energy than flame and returns roughly 20% more remains to the family.

At Passing Paws, this is the only method we use. We chose it because it's gentler — gentler on the body, gentler on the planet, and, we think, gentler on the families who have to picture the process at all.

Is pet cremation legal in California?

Yes. Both flame and water-based cremation are fully legal and regulated for animals in California. Aquamation has been legal for pets in the state for years and is also approved for human use in California as of 2017. Any reputable provider in Los Angeles should be able to show you their licensing and walk you through their chain-of-custody process without hesitation.

Individual vs. communal cremation

This is the most important distinction to understand before booking, because it determines whether your pet's ashes come back to you.

• Individual cremation means your pet is processed alone. The remains returned to you are entirely your pet's. At Passing Paws this starts at $349 and includes a cedar urn, fur clipping, clay paw print, and certificate.
• Communal cremation means your pet is processed alongside other pets. Remains are not returned — they are respectfully scattered. This is a beautiful, dignified option for families who don't want ashes at home. Ours is a flat $179 regardless of size.

Neither choice is "better." Some families want their pet's ashes on the mantel or in a piece of jewelry. Others find peace in letting their pet's body return to the sea. Both are acts of love.

What to expect: the timeline

Most families want to know two things — how soon someone can come, and how long until they get their pet back. Here's the honest answer:

• Pickup: Same day in almost all cases. Our hours are 8am–8pm seven days a week, with after-hours pickup available. If your pet passes overnight, you can keep them comfortable at home (see our guide on what to expect when your pet passes at home) and we'll come first thing in the morning.
• The process itself: 6–8 hours of warm-water treatment, followed by gentle drying and processing of the mineral remains.
• Return to you: 5–7 business days from pickup. Rush processing (3 days) is available for an additional fee.

Throughout this time, your pet wears a stainless steel ID tag that stays with them from pickup through return. We're a small team, and we take that chain of custody seriously.

What you actually receive

With every individual cremation at Passing Paws, families receive:

• A handcrafted cedar urn holding the ashes
• A handmade clay impression of your pet's paw
• A clipping of your pet's fur, preserved in a small envelope
• A handwritten certificate of aquamation

The ashes from water-based cremation are notably finer and lighter in color than flame-cremation ash — more like sand or fine bone meal than gray dust. Many families tell us they find this version easier to look at.

Common myths, briefly addressed

"They mix the ashes." Reputable providers don't. Ask any cremation service to walk you through their identification system before you commit. Ours uses individual stainless steel tags from pickup through return.

"Aquamation isn't real cremation." Legally and practically, it is. It produces the same kind of remains — mineral ash — through a different process. The American Veterinary Medical Association recognizes it as a valid aftercare method.

"There won't be enough left of a small pet." Even with a hamster or a bird, there are remains. The volume is small, but it's real, and we return all of it.

The environmental piece

If this matters to you, it's worth knowing the numbers. A single flame cremation uses roughly the natural gas equivalent of a 500-mile car trip. Water-based cremation uses about 10% of that energy, releases no emissions, and uses a fraction of the water of a household washing machine cycle. For families in LA who try to live thoughtfully, aquamation is often a quiet relief — a way to honor their pet that fits their values.
