In a room inside a North Hollywood warehouse, dozens of pets are ready for their owners to take them home.

Boots, a young black-and-white domestic shorthair cat, lies on his back, pawing playfully at the air. A trio of red, yellow and green parrots and cockatiels sit on wooden perches, oblivious to the piercing stare of a blue-eyed feline a few feet away. Princess, a senior Chihuahua, rests with her eyes closed and body curled into a tight cocoon, as a frenetic hamster named Ponby stands upright, his eyes bulging. There’s a naked guinea pig, a giant red macaw and an adorably chunky pit bull named Messy.

Eyes, such as those shown here on Messy the pit bull, are made of glass and closely match the animal’s original colors.

All of these animals are loose, liberated from the confines of cages and leashes, and yet no havoc has ensued.

These animals are also all dead.

It’s an everyday scene at Bischoff’s the Animal Kingdom, a Los Angeles taxidermy business that has been preserving animals for 103 years. The business is multifold — Bischoff’s creates and rents out prop animals to film studios, museums and nature centers. Posters on the lobby walls boast the company’s work on shows like “American Horror Story” and “Westworld.” But in recent years, a bulk of its taxidermy requests now come from bereaved pet owners, those willing to shell out thousands of dollars for a tangible commemoration of their late “fur babies.”

Birds are commonly preserved at Bischoff’s, but the business has made mementos of more obscure pets, including chameleons, roosters and hairless guinea pigs.

From full-body taxidermy to partial mementos — skulls, bronzed hearts or freeze-dried paws, for example — such services provide closure in ways that, clients say, traditional burials or urns cannot.

“It was honestly really comforting to have her back, and just be able to touch her and, in a sense, talk to her too,” said Bischoff’s customer Zoe Hays of the preservation of her Chihuahua-Yorkie mix Pixie. “She was a great little dog — also a menace to society, for sure — but she’s still with me, and she always will be.”

Bodily preservation, beyond the ashes or cemented paw prints offered by veterinarians and animal hospitals, has become a growing facet in the world of pet aftercare, with traditional taxidermists fulfilling many of the niche requests.

Inside Bischoff’s, the L.A. taxidermy company that preserves dead pets

Redlands business Precious Creature initially only offered full-body taxidermy of pets until customers started suggesting other ideas, such as lockets containing patches of fur and cat-tail necklaces. (Most recently, owner Lauren Kane sewed a zippered pillowcase using the black-and-white fur of a rescue named G-Dog, or, as his owner fondly called him, “Fluffy Butt.”) In her documentary “Furever,” filmmaker Amy Finkel explores the lengths to which pet preservationists will go, asking, “Who decides what kind of grief is acceptable, or appropriate?”

Bischoff’s co-owner Ace Alexander had a songwriting career before transitioning to taxidermy.

Ace Alexander, 40, and Rey Macias, 55, the fourth owners in Bischoff’s long history, have steered the company to meet the new demand. Describing each other as “good friends,” the two men dress similarly in unofficial uniforms of black T-shirts and black pants, and they’re so in sync they sometimes finish each other’s thoughts. Since taking over the business, both have transitioned to primarily vegan diets.

“Bischoff’s used to be taxidermists to the stars in the trophy era, but now we’re taxidermists in the pet preservation era,” Alexander said. “People no longer hunt. Now they just love their pets.”

Hollywood needs supporting actors, even if they’re stuffed

Over the decades, Bischoff’s has preserved hundreds of animals. The Sumatran tiger has made many appearances in films and TV shows, including “Snowfall,” “Palm Royale” and “Welcome to Chippendales.”

In 1922, when Al Bischoff first opened the business on Sunset Boulevard in Hollywood, he’d stuff and plaster any animal brought to him. Most of the time, that meant trophies from hunting and safari trips, but it also included beloved pets owned by Hollywood elite. Roy Rogers used Bischoff’s to preserve his co-stars Trigger the horse and Bullet the dog. Buck — the dog from “Married with Children” — also got the Bischoff’s treatment.

Under Alexander and Macias’ tutelage, that’s still the case. They’ll preserve any animal you bring them — so long as it is not a protected species or an illegal pet. They’ll even make you a unicorn or a sasquatch or a wearable Velociraptor costume that roars and can open and close its jaws. The largest animal Alexander and Macias have preserved was an 11-foot-long buffalo, while the smallest, not including insects, was a hummingbird. Off the top of their heads, the only animal they haven’t preserved — yet — is the genetically rare white tiger.

The majority of Bischoff’s clientele still comes from Hollywood. Due to federal and state laws, as well as industry regulators like the American Humane Association, it often makes more sense to use body doubles for animals when filming and is occasionally mandatory (such as scenes that involve roadkill or drowning incidents).

On a recent Wednesday, Alexander fielded calls from studios about the types of snake skins in stock, how to clean dirt off a rented coyote and the particular body poses of their turkeys.

“So what are you thinking?” Alexander said, talking on the phone. “Turkeys in flight? Perched? Or did you need a floppy version?”

As for the pet sector, which accounts for around 40% of their business, dogs and cats, unsurprisingly, make up the majority of the preservations, but the team has also worked on rabbits, rodents, chameleons and roosters. And although they will preserve your pet goldfish, they will strongly encourage you to consider having a synthetic version made of it due to the oils in the scales, which inevitably lead to deterioration.

Bischoff’s works on pets shipped from around the country as well as overseas. Dr. Xanya Sofra, who is based in Hong Kong, has had at least half a dozen of her papillons preserved by Bischoff’s. Another client, who was an avid hiker, had Bischoff’s preserve his golden retriever in an upright position so that he could carry it in his backpack on his treks.

Neither Alexander nor Macias had a background in taxidermy when they started working at Bischoff’s. They were both musicians, which is how they initially met. Macias also owned an auto shop and has been taking apart and fixing appliances from a young age.

Alexander picked up jobs at Bischoff’s when it was owned by the previous owner, Gary Robbins. The pay was good, the work interesting and he realized he had a knack for airbrushing and sculpting. In 2017, when Robbins was ready to retire, Alexander and Macias, who by then had also started working there, decided to buy the business.

Blending artistic skill with scientific knowledge

Each multi-level freeze-dryer can fit around a dozen pets at a time. Smaller pets need three to four months to dry out, while larger animals take nearly a year.

Bischoff’s specializes in a form of hybrid taxidermy, incorporating traditional techniques with the more new-fangled freeze-drying process. The results are not only more lifelike and long-lasting than the standard gut-and-stuff method, but it also allows for the bulk of the original animal to remain, including the skeletal structure, toenails, whiskers, eyelids, nose and teeth. The eyes, however, are made of glass.

The method leaves room for error. Water can be used to dampen and repose the body and paint can be removed or retouched.

“You can definitely backpedal,” Alexander said, making a note to check the texture of the preserved hearts on sticks in the next 24 hours.

Alexander credits this attention to detail to his predecessors, former owner Robbins and then-main taxidermist Larry Greissinger, who taught him the trade. Strict in their teachings, Robbins and Greissinger emphasized getting every bodily facet correct: from recreating the natural anatomy to sewing the perfect hidden stitch to making sure the eyes looked right.

“That’s where the emotion is,” Alexander said. “You can get the perfect body pose, but if the eyes aren’t sitting well or don’t carry any emotion, then the animal will never look alive.”

Bischoff’s has old and new taxidermy, including two polar bears from the 1940s and 1950s, a bull created in 2013 for the “Yellowstone” prequel “1923” and a buffalo that appeared in “The Lone Ranger.”

A few of Bischoff’s early taxidermy pieces are still on display, including a dog, which looks more like a cross between a wolf and a baboon, dating to the 1920s. Its plaster interior, an old taxidermy technique, gives it a stiff visage and makes it exceedingly heavy.

Bischoff’s prices reflect its modernized techniques, as well as the amount of time and attention to even the smallest of details required to make a dead pet come back to life. The cost for a fully preserved cat or a small dog like a Chihuahua starts at $2,640, with small birds, like a budgie, starting at $850.

Although most customers order full-body taxidermy, an “a la carte” menu has expanded over the years with jars of whiskers or fur, bundles of bones tied in a bow and, the most recent addition, freeze-dried hearts, which come mounted inside of a glass cloche. Bischoff’s also offers cloning services through its Texas-based affiliate Viagen Pets, to whom they send the pet’s skin tissues.

Pelts, paws and bronzed skulls are among the smaller items purchased by pet owners.

Costly though their work is, Alexander and Macias see it as an investment. Pets, they point out, are friends you look at every day. You’re intimately aware of their nuances and quirks, like how their left ear might curl back more than the right one or the way their nose tilts ever-so-subtly upwards. Entrust their preservation to a novice or lower-cost taxidermist, and you risk losing some of the elements that made your pet who they were.

Bischoff’s has seen its share of people who’ve preserved their pets with budget taxidermists only to be disappointed. “It’s unfortunate because at that point, there’s not much we can do,” Alexander said. Such pets are cremated “because they just can’t stand to look at them.”

Bischoff’s key component? Compassion

In the back of Bischoff’s warehouse is where the equipment resides and the smells of the oils running the machines permeates the space. The company has one aquamation machine that uses alkali solution, heat and pressure to break down the organic material into ashes. With interior chambers lined with perforated metal walls, the contraption somewhat resembles a fast-food restaurant’s deep fryer. Except, one taxidermist notes, when the process is done, instead of having golden fried potato strips in each basket, all that is left are bones.

Oftentimes at the ends of these processes, Bischoff’s workers will find inorganic remnants from the pets, such as microchips, metal plates or orthopedic screws. They give them to their owners as keepsakes.

Macias’ son, 29-year-old Chris Macias, works alongside his dad at Bischoff’s. He started helping out to make extra money while attending nursing school, but when business picked up, he decided to transition fully into the taxidermy business. He does a little bit of everything — recently, it was prepping a seal pelt for the San Pedro Marine Mammal Care Center — but tends to do pet pickups the most. Less technical though it may be, it is more emotionally taxing as he’s interfacing with grieving clients who might still be in shock or confused as to what exactly they want to do with their late pets.

Two calico cats were returned to Bischoff’s by the children of the woman who owned them after her death.

“Everybody’s different, but I just try to be there for them,” Chris said. “Their pet was part of their family, so I totally understand. Because all of us here, we have our own pets as well. We get it.”

Though Alexander never imagined building a career out of preserving dead pets, he said, “We’ve found joy in this work and we just see preservation as another form of art.”

It’s that art that is helping keep the memories of beloved pets alive — for generations even. Hays, the owner of Chihuahua-Yorkie mix Pixie, already has a contingency plan in place for Pixie’s taxidermy upon her own death. It will be “adopted” by another family member. Her daughter has already called dibs.

And many of Bischoff’s pet preservation customers are repeat clients, which is something that Alexander and Macias take pride in. Two women picking up the taxidermy body of their late cat recently chatted with Alexander about their newest rescue, a diabetic stray cat burnt in the Altadena fires. They couldn’t help but comment on the “beautiful bone structure” of the feline, still very much alive.

“I was like, ‘Hmm, you’re definitely going on the altar some day,’” one of the women said.
