Biodegradable Pet Caskets

Materials and Construction

Biodegradable pet caskets are crafted from natural materials including handmade parchment, woven fabric, and natural fiber composites. Our most popular line features flower petals pressed directly into the parchment exterior, creating a unique, handcrafted appearance. Interiors are lined with soft fleece in coordinating colors, providing a comfortable and dignified resting place. Unlike a cultured pet casket or pet metal casket, biodegradable caskets are designed to break down naturally — returning your companion to the earth over time. Some families also find that a cardboard pet coffin or natural fiber option offers a meaningful alternative to traditional materials at a lower price point.

Fish Caskets and Goldfish Caskets

We carry biodegradable caskets designed specifically for aquatic pets. Our fish casket is shaped like a fish and crafted from natural materials, providing a fitting tribute for a beloved aquarium companion. The goldfish casket is a smaller version designed for goldfish and other small fish. Both are fully biodegradable and can be used for earth burial in a garden or yard. Fish coffin options start at $39.95 and are among our most popular biodegradable products, giving families a meaningful way to say goodbye to a pet that brought joy and calm to their home.

Sizes for Dogs, Cats, and Small Animals

Biodegradable pet burial boxes are available in five sizes ranging from 12 inches to 32 inches in interior length. The smallest size fits hamsters, birds, guinea pigs, and other pocket pets. Medium sizes (19 to 24 inches) accommodate cats and small to mid-size dogs. The largest biodegradable box for pet burial (32 inches) fits dogs up to approximately 70 to 80 pounds. If you need a larger casket for a big breed, our wood pet caskets offer larger options — and wood will also biodegrade naturally over time, though more slowly.

Earth Burial vs. Sea Burial

Earth Burial: Biodegradable pet caskets are ideal for backyard burial or natural pet cemeteries that allow green burial. The casket will break down in soil over months to years depending on material and conditions, allowing your pet to return naturally to the earth. For guidance on burial depth, location, and local regulations, see our guide on how to bury a dog.

Sea Burial: Some families choose to lay their pet to rest in a body of water. Biodegradable caskets will dissolve in water more quickly than in soil, making them suitable for ocean, lake, or river burial where permitted. Check local regulations before conducting a water burial, as rules vary by location.

Memorial Services: Despite being biodegradable, these caskets are sturdy enough for a brief viewing or pet funeral service before burial. The flower-petal parchment exterior and fleece interior create a dignified presentation.
