(Press-News.org) Two pioneering studies published in the journal Animals have explored how dog and cat guardians perceive more sustainable pet food options.
Co-led by Griffith University Adjunct Professor Andrew Knight, the research sheds new light on the potential for alternative proteins and plant-based diets in the companion animal sector.
Study One – Dogs: ‘Consumer Acceptance of Sustainable Dog Diets: A Survey of 2,639 Dog Guardians’
In the first study, the team surveyed 2,639 dog guardians worldwide.
About 84 per cent of respondents were currently feeding their dogs either conventional or raw meat-based diets.
However, a substantial 43 per cent of this group reported they would nevertheless consider at least one type of more sustainable dog food (such as vegan, vegetarian or cultivated-meat formulations).
Among the alternative options, the most acceptable was cultivated meat-based dog food which was real animal meat produced by growing animal cells in a controlled environment (chosen by 24 per cent of these respondents), compared with vegetarian (17 per cent) and vegan (13 per cent) dog diets.
When asked what characteristics would be needed for these alternatives to be chosen, the top choices were nutritional soundness (chosen by 85 per cent) followed by good pet health (83 per cent).
Study Two – Cats: ‘Consumer Acceptance of Sustainable Cat Diets: A Survey of 1,380 Cat Guardians’
The companion study gathered responses from 1,380 cat guardians.
In total, 89 per cent of these guardians fed their cats conventional or raw meat-based diets.
However, more than half – 51 per cent – of this group considered at least one of the more sustainable options to be acceptable.
The most popular alternatives were those based on cultivated meat (chosen by 33 per cent of this group) followed by vegan diets (18 per cent).
Similarly to dogs, the most important characteristics alternative diets would need to offer to be chosen were good pet health outcomes (chosen by 83 per cent) and nutritional soundness (80 per cent).
Differences among consumers
Both studies found guardians who themselves reduced or avoided meat were significantly more open to alternative diets for their pets, as were those with higher educational qualifications.
Age and regional differences were also apparent, with older consumers, and those from the UK, often less open to alternatives than those in other European nations, North America or Oceania, although differences were often not significant.
What this means
Professor Knight said the studies came at a time when the environmental and ethical footprint of conventional pet food production was growing in public consciousness.
“Recent studies have demonstrated our dogs and cats collectively consume a substantial proportion of all-farmed animals,” he said.
“Pet diets such as those based on plant-based ingredients or cultivated meat could transform the pet food system, lowering adverse impacts for farmed animals and the environment.”

A new method for the synthesis of giant fullerenes
2025-11-19
Professor Zaifa Shi's team at Xiamen University developed an ultra-high temperature flash vacuum pyrolysis (UT-FVP) device to form giant fullerenes from single-carbon molecules within a short time (15 s) at extremely high temperatures (∽3000 ℃). Due to the strong intermolecular forces between giant fullerene molecules and soot, traditional ultrasonic or Soxhlet extraction methods cannot separate most giant fullerenes from soot in toluene. To overcome these strong intermolecular forces, two ...
National team works to curb costly infrastructure corrosion
2025-11-19
The University of Florida is part of a multi-university, interdisciplinary research team that will tackle the global challenge of halting corrosion of infrastructure, like bridges.
Mitigating corrosion is a global challenge that costs the United States nearly half a trillion dollars annually.
Current corrosion mitigation measures require costly chemical coatings, such as primers and top-coat layers, that cause human and environmental health risks. This project seeks to develop a coating system that uses naturally existing microbial biofilms growing on metal surfaces ...
A ‘magic bullet’ for polycystic kidney disease in the making
2025-11-19
(Santa Barbara, Calif.) — Polycystic kidney disease (PKD) is a debilitating hereditary condition in which fluid-filled sacs form and proliferate in the kidneys. Over time, the painful, growing cysts rob the organs of their function, often leading to dialysis in advanced cases There is currently no cure.
Researchers at UC Santa Barbara, however, have proposed a cyst-targeted therapy that could interrupt the runaway growth of these sacs by leveraging the target specificity of the right monoclonal antibodies — lab-made proteins that are used in immunotherapy.
“The cysts just keep growing endlessly,” said UCSB biologist ...

Seismic sensors used to identify types of aircraft flying over Alaska
2025-11-19
An array of seismic sensors deployed to capture aftershocks from the 2018 magnitude 7.1 Anchorage earthquake also collected distinctive signals from hundreds of flights crossing over Alaska.
In their study published in The Seismic Record, Isabella Seppi and colleagues at the University of Alaska Fairbanks show that these signals can be used to identify the type of aircraft, along with details such as the closest time, distance and speed of each plane or helicopter as it flew above the seismic array.
Acoustic waves generated by flying aircraft vibrate the ground below, transforming sound energy into ground motion that can ...

The Lancet: Experts warn global rise in ultra-processed foods poses major public health threat; call for worldwide policy reform
A new three paper Series published in The Lancet reviews evidence that ultra-processed foods (UPFs) are displacing fresh and minimally processed foods and meals, worsening diet quality, and are associated with an increased risk of multiple chronic diseases.
The Lancet Series on Ultra-Processed Foods and Human Health argues, although additional studies on the impact of UPFs on human health will be valuable, further research should not delay immediate and decisive public ...
Health impacts of eating disorders complex and long-lasting
2025-11-19
The health impacts of eating disorders, such as anorexia, bulimia, and binge eating, are not only complex, affecting many different organ systems, but long-lasting, finds a large tracking study, published in the open access journal BMJ Medicine.
The risks of serious conditions, such as diabetes, renal and liver failure, fractures, and premature death, are particularly high within the first 12 months of diagnosis. But these heightened risks persist for years, highlighting the need for timely integrated multidisciplinary health services and continued monitoring to improve outcomes, conclude the researchers.
UK rates of eating disorders ...

Ape ancestors and Neanderthals likely kissed, new analysis finds
A new study led by the University of Oxford has found evidence that kissing evolved in the common ancestor of humans and other large apes around 21 million years ago, and that Neanderthals likely engaged in kissing too. The findings have been published today (19 November) in Evolution and Human Behavior.
Kissing occurs in a variety of animals, but presents an evolutionary puzzle: it appears to carry high risks, such as disease transmission, while offering no obvious reproductive or survival advantage. Despite kissing carrying cultural ...
Ancient bogs reveal 15,000-year climate secret, say scientists
2025-11-19
Scientists have revealed that ancient bogs in the Southern Hemisphere hold clues to a major shift in the Earth's climate thousands of years ago.
Researchers looking at peatlands have discovered that sudden shifts in the Southern Westerly Winds 15,000 years ago triggered a massive growth of the swamps.
Geo-experts have never fully understood what caused the bogs to form across the Southern Hemisphere after the last Ice Age.
But the scientists behind the new paper, published in Nature Geoscience, now ...
