Living memorials in Centennial: the local picture
Dry air, strong sun and repeated freezing and thawing wear down outdoor memorials in Centennial. Natural stone and bronze hold up; painted concrete and resin may crack over a few winters. If you plan to plant a tree urn, choose a species suited to Front Range conditions and plant in spring, after the risk of hard frost. Water it through the first couple of summers.
Centennial homes typically have backyards with lawn and garden beds, so outdoor memorials are an easy option for many families. A flat granite stone, a boulder with an engraved plaque or a small memorial garden can all fit. Check any HOA guidelines before installing something visible from the street. Inside, an urn beside a paw print frame or a small memory box fits any room.
If you'd like water cremation, Centennial is the kind of place where it may be offered by one local provider or by a larger centre such as Aurora. It's worth one phone call to find out. Some aquamation providers collect from a vet clinic across a wide area, and turnaround is usually measured in days to a couple of weeks rather than hours, so there's no need to decide anything in the first evening.
With roughly 108,658 residents, Centennial is the 11th-largest of the 36 Colorado communities we cover. The nearest larger centre is Aurora, about 10 miles (16 km) away, which is where some providers serving Centennial are based.
Nearby, we also have local pages for Parker (8 miles), Englewood (8 miles) and Littleton (8 miles), which can help if your vet or the provider you prefer is based there.
Our estimate
40,000
Estimated dog- or cat-owning households in Centennial
How we calculated this
108,658 ÷ 2.5 = 43,463 households; × 53% (dog) + 39% (cat) = 40,000. Multi-pet homes count once.
Our estimate
3,350
dog and cat deaths per year in Centennial, our estimate
How we calculated this
40,000 dog/cat-owning homes ÷ average lifespan (dog: 12.69 yrs + cat: 11.18 yrs) ≈ 3,350 a year. A floor, not a ceiling.
53%[1]
53% of US households own a dog, which is about 71 million households.
12.69 years[2]
US dogs have an average life expectancy at birth of 12.69 years.
39%[3]
39% of US households own a cat, which is about 53 million households.
11.18 years[4]
US cats seen at Banfield hospitals have an average life expectancy at birth of 11.18 years.

The local attitude to ashes and memorials
Because cremation is the norm in Colorado, at roughly 77.4%[5] of deaths, green ideas about ashes are easy to raise without raised eyebrows. In the US, 68%[6] of people in NFDA's 2024 consumer survey expressed interest in green funeral or natural burial options. If you'd like the lower-impact route for a pet, start with the cremation method, then choose an urn that breaks down and a native plant.
The Colorado percentage above is from NFDA 2024 Cremation & Burial Report state projections (via Occasional Sage) (2024) and refers to human funerals. Treat it as context for Centennial, not as a count of pets.
Weather, soil and planting windows in Centennial
A Centennial winter is a useful waiting room. With 5 months of freezing lows, you can mix the ashes with compost in a covered bin or tub in a garage or shed during the cold months and let the mix rest. One gardening guide suggests at least 90–120 days[7] before planting, which fits neatly between a winter loss and spring planting. Test the pH before the tree goes in.
Water releases need open water, and in Centennial lakes and ponds may ice over around January. Never walk out onto ice to release an urn. If a lake or river was your pet's place, plan the release for spring or summer, when the shoreline is safe and a water-soluble urn can float and dissolve as it's meant to. Keep the ashes at home until then.
Adding up the cost of a bio urn memorial in Centennial
The container the ashes come back in can quietly add to the bill. One Virginia crematory, for example, sells private cremation at $189 with a temporary container and $225 with a wooden urn[8]. If you're planting, the plain option is all you need. Wooden pet urns alone run about $30–$150[9] in one national guide, money that could buy a good tree for your Centennial garden instead.
Rather than repeat the price table on every city page, we keep one for Colorado: Colorado costs. What each service includes is on the services page.

Scattering and planting rules in Colorado
Two questions cover most situations in Colorado: who owns or manages this land or water, and have they said yes? For your own garden, the answer is you. For a rented home, it's your landlord, in writing. For parks and public water, it's the relevant agency. For a relative's garden, it's them, and it's worth agreeing that the tree stays even if the house is sold.
Colorado keeps an official directory of local governments; use it to reach the county or city office that covers Centennial.
The rules that apply across Colorado (home burial, scattering and who oversees pet cremation) are summarized on our Colorado page. Centennial may add its own conditions, so check with the city or county before digging.
Your next steps, whatever your situation
- Decide what the memorial is for. Wanting somewhere to sit, a living plant, a release on water or simply the gentlest footprint each leads you toward a different kind of urn.
- If a greener cremation matters, ask about aquamation before anything else; it's the step with the biggest environmental difference.
- Keep a small portion back in a keepsake in case a house move or a second memorial is on the cards down the line.
- Buy the tree locally. A young native tree from a grower around Centennial tends to outgrow anything sprouted from a packet seed.
- Prepare the soil a season ahead if the timing allows, so the ash and compost blend is ready on planting day.
- Plant with the people who loved your pet, and give each of them a job: mixing, filling, watering.
Remembering your pet, in Centennial and wherever you go next
Many Centennial families have relatives spread across the Denver metro and beyond, and memorials that can be shared are popular. Splitting the ashes into several small containers, or ordering several copies of a paw print, lets everyone have something. Jewelry holding a tiny amount of ashes is another option, and it suits relatives who live far from Arapahoe County. Ask about these choices before cremation takes place, because portions are easiest to prepare at the start.

Questions people ask
Where are the providers that serve Centennial actually based?
Some are local, and some run from Aurora, about 10 miles away. That is normal for a city this size. What matters is the collection time they quote for Centennial and whether the drive is priced into the total, so ask both up front.
Is cremation common in Colorado?
For people, yes: about 77.4%[5] of Colorado deaths end in cremation, according to NFDA 2024 Cremation & Burial Report state projections (via Occasional Sage) (2024). Nobody publishes the same figure for pets, but in our experience pet choices in Centennial follow the human pattern closely, so cremation is the default most families here start from.
How does Centennial's weather affect pet aftercare?
July is the hottest month in Centennial, with average highs around 90°F, so prompt collection matters most then. Average lows drop below freezing in January, February, March, November and December, which can make digging a grave hard until spring.
Roughly how many pets die in Centennial each year?
Our estimate is around 3,350. It comes from Centennial's population (about 108,658), the average household size, the share of homes with a dog or cat (about 40,000 households here) and the average lifespan. It is arithmetic, not a count, so read it as a rough floor.
Is it safe to plant a fruit tree with my pet's ashes?
Cremated remains are mostly bone minerals, and once they're thoroughly blended into plenty of compost and garden soil, many gardeners grow fruit trees over them. The high pH and salt are the real concern for the tree, so dilute generously and test the pH. If eating fruit from the memorial feels wrong to anyone in your family, choose an ornamental tree instead.
Is water cremation better for the environment?
It uses much less energy: pet aquamation is claimed to use about 90%[11] less energy than flame cremation, and it uses about as much water as 1–3 pet baths[12] per pet. The strongest carbon figures come from studies of human funerals, not pets, so treat them as a direction rather than a promise. You still get ashes back for a bio urn.
