Pet ownership in Australia has surged during the past few years of COVID-19 lockdowns.
It has meant the pet food industry — worth an estimated $2.74 billion annually and growing rapidly — is struggling to keep up.
"Pet ownership has been growing in Australia year on year, but with COVID we saw a considerable uptick," Emily Dowling of Mars Petcare said.
"About 60 per cent of Australian households had a pet before COVID. Now it's about 70 per cent."
More furry mouths to feed
The Australian arm of the global company produces about 100,000 tonnes of meat products each year and is seeing record demand for protein of every sort.
Australian sales are at an all-time high, and export sales into Asia have also seen substantial growth.
The pet food industry operates hand-in-glove with the human food chain. In essence, humans get the prime cuts, while pets get the bones and body parts.
At present, slaughter numbers for cattle and sheep are well down as producers seek to rebuild following the recent drought.
That means lower volumes of offcuts and offal and subsequently increased competition among pet food producers.
Insects used for protein
Dr Stubbe is a vet and pet food manufacturer which, for several reasons is, producing dog biscuits made from insect protein derived from black soldier fly larvae.
Soldier flies are extremely efficient at converting waste into protein — in this instance, domestic waste gathered across Melbourne — and insect proteins provide nutrients often lacking in red meat.
"They're 12 to 25 times more efficient at converting feed to a kilo of protein versus cattle, so it says a lot, and I'm from a beef farm, so I'm an advocate for the beef industry," Dr Stubbe said.
As yet, unusual proteins such as insects are only a small segment of the market but, overall, pet food mirrors trends in human nutrition. Most pet food companies are also introducing vegetarian or non-animal-based pet products to their ranges.
"[The trend is moving] back to natural, minimal ingredients, minimal processing and without the big, long list of ingredients on the ingredients panel on the back of the pack," said Edward Staughton, of the Staughton Group, one of the giants of the Australian pet food industry.
From pigs' ears to dog biscuits
The company's pet food manufacturing plant at Howlong, southern New South Wales, employs about 400 people, and it has plans to expand.
The facility processes offcuts and offal collected from about 30 abattoirs across Australia and turns them into about 300 product lines — everything from dehydrated pigs' ears and chicken feet to dog biscuits and kibble.
Nothing goes to waste. Every skerrick of usable protein is extracted and utilised, many of them animal parts once discarded into landfill.
They include bizarre items such as bull's pizzles, which are marketed as "bully sticks" and are a bestseller in the United States.
The company's quest for additional protein sources has seen it begin to process feral animals such as pigs and deer. The harvester and the landholder get paid for each carcase, and the meat is lean and nutritional.
Health-conscious owners
Pet owners are becomingly increasingly conscious about their pets' nutrition. It is a trend pet store owner Diane Ingrey, of Albury, has seen for two decades.
"You've got your 'roo sternums — a wonderful, natural Australian product — things like your fish knots — just knotted and dried, nothing else in there — then there's your turkey legs and then things like your turkey necks — so beautiful for a dog to chew on," said Ms Ingrey.
Our perceptions of pets and how we treat them have also changed, especially since COVID-19 lockdowns.
"When we started in 2004, the dogs were in the backyard, and now they've progressed to the house and into people's bedrooms," Ms Ingrey said.
In the offices of Mars Petcare at Wodonga, dogs sit contentedly next to their owners. The company's pet-friendly approach is gaining popularity in workplaces.
"We generally understand that our productivity, our effectiveness, our engagement levels are actually elevated with the presence of pets in the office," Shane Byrne, of Mars Petcare, said.
Pets have never had it so good. And we as humans have never loved them so much.
