The world of cat care is about to undergo a significant transformation. For the first time, researchers have shown that video telehealth visits can be an effective way to improve the quality of life for cats suffering from chronic health conditions. The study, conducted by a team at the University of California, Davis, involved 106 pet owners whose cats had mobility issues and found that these virtual consultations significantly benefited both cat and owner.

According to lead author Grace Boone, an assistant specialist in the UC Davis Animal Welfare Epidemiology Lab, “Teleadvice is meant to provide advice and support for caregivers caring for their cats.” The results of the study, published in Frontiers in Veterinary Science, demonstrate that video calls where pet owners can ask questions and get non-medical advice can be beneficial. In fact, more than 95% of those who took part in the research said they would pay for telehealth visits, though most were willing to pay a little less than for in-clinic appointments.

A common ailment affecting cats is feline arthritis, which affects roughly 6% to 30% of cats under age 10 and from 64% to 92% of those older than 10. As Carly Moody, senior author on the paper and an assistant animal science professor, points out, “Cats are great at hiding signs of pain.” This means that chronic health issues can go undetected for a long time if owners don’t seek veterinary care.

The researchers found that video telehealth visits allowed pet owners to receive guidance on how to modify their home environment to improve their cat’s mobility and comfort. Suggestions included elevated food and water dishes, larger litter boxes with shorter walls, and additional steps to access favorite places. Pet owners reported that the visits helped them understand their cats’ needs, making them more confident in how they cared for their cats.

Telehealth visits don’t require a veterinarian; a registered veterinary technician or other knowledgeable staff member can conduct the calls, answer questions, and give advice. These consultations are meant to supplement, not replace, in-person veterinary care. In fact, the visits have the potential to foster better veterinarian-client-patient relationships by improving communication and understanding between cat owners and veterinarians.

Future research will examine whether recommended changes based on expert advice can improve a cat’s wellbeing in the home. Additionally, Moody’s lab may explore whether telehealth could be beneficial for other health issues like obesity and disease prevention.

This article highlights the potential benefits of video telehealth visits for cats with chronic health conditions and emphasizes the importance of exploring new ways to provide care that prioritizes animal welfare.

Can Dogs See Through a Person’s Kindness? A Surprising Study Says No

Despite our strong belief in dogs’ ability to sense good from bad in people, new research shows they may not actually judge human character, at least not in the way we think. When dogs watched how humans treated other dogs, they didn’t favor the kinder person later. Even direct interactions didn’t sway their behavior. The study suggests dogs’ reputational judgments might be more nuanced—or harder to study—than we realized.

As we often assume that dogs can gauge a person’s character based on their behavior towards them, scientists have long been fascinated by this aspect of canine cognition. However, a recent study conducted at Kyoto University in Japan has revealed that dogs may not be as perceptive as we think.

The researchers involved 40 pet dogs in the study to investigate how age and development influence their ability to form reputations of humans. The dogs were first exposed to observing another dog’s interactions with two humans, one of whom provided food while the other did not. After this indirect experience, the dogs then interacted directly with both humans.

Surprisingly, the results showed that the dogs did not display a significant preference for the generous person who fed them compared to the selfish person who refused to feed them. The dogs’ behavior towards both humans was random and did not exceed chance levels following either indirect observation or direct interaction.

“This study highlights the methodological challenges in accurately capturing dogs’ understanding and evaluation of humans,” said corresponding researcher Hoi-Lam Jim, who recently joined the faculty at Kyoto University. “It’s clear that reputation formation may be more complex than previously thought, even for animals like dogs that closely cooperate with humans.”

While this study did not provide conclusive evidence of dogs forming reputations of humans, it emphasizes the need for further research to better understand what influences their sociocognitive abilities. Future studies should aim to systematically compare dogs of all ages from different populations and life experiences.

In conclusion, while we often assume that dogs can see through a person’s kindness, this study suggests that our furry friends may not be as perceptive as we think. Perhaps it’s time to reevaluate how we understand canine cognition and give them the benefit of the doubt.

Florida Cat’s Latest Catch: New Virus Discovered in Shrew

A cat named Pepper has once again helped scientists discover a new virus—this time a mysterious orthoreovirus found in a shrew. Researchers from the University of Florida, including virologist John Lednicky, identified this strain during unrelated testing and published its genome. Although once thought to be harmless, these viruses are increasingly linked to serious diseases in humans and animals. With previous discoveries also pointing to a pattern of viral emergence in wildlife, scientists stress the need for more surveillance—and Pepper remains an unlikely but reliable viral scout.

The University of Florida’s Pepper, the pet cat who made headlines last year for discovering the first jeilongvirus found in the U.S., has done it again. This time, his keen senses have led researchers to a new strain of orthoreovirus, which is known to infect humans, white-tailed deer, bats, and other mammals.

John Lednicky, Ph.D., Pepper’s owner and a University of Florida College of Public Health and Health Professions virologist, was testing a specimen from an Everglades short-tailed shrew when he stumbled upon the new virus. The discovery came as part of his ongoing work to understand transmission of the mule deerpox virus.

Lednicky’s team published the complete genomic coding sequences for the virus they named “Gainesville shrew mammalian orthoreovirus type 3 strain UF-1” in the journal Microbiology Resource Announcements. The researchers note that while there have been rare reports of orthoreoviruses being associated with cases of encephalitis, meningitis, and gastroenteritis in children, more research is needed to understand their effects on humans.

“We need to pay attention to orthoreoviruses and know how to rapidly detect them,” Lednicky said. “There are many different mammalian orthoreoviruses, and not enough is known about this recently identified virus to be concerned.”

Pepper’s contributions to scientific discovery continue unabated. His specimen collection has led researchers to the identification of two other novel viruses found in farmed white-tailed deer, highlighting the importance of continued research into the ever-evolving world of viruses.

The discovery of new viruses is not surprising, given their propensity to constantly evolve and the sophisticated lab techniques used by researchers like Lednicky. “If you look, you’ll find,” he said. “And that’s why we keep finding all these new viruses.”

Lednicky and his team plan to conduct further research into the new virus, including serology and immunology studies to understand its potential threat to humans, wildlife, and pets.

Meanwhile, Pepper remains healthy and continues to contribute to scientific discovery through his outdoor adventures. As Lednicky said, “If you come across a dead animal, why not test it instead of just burying it? There is a lot of information that can be gained.”

The Nano-Colors of Blue Sharks: Unveiling the Secrets of their Iconic Blue Pigmentation

Blue sharks possess a secret hidden in their skin: a sophisticated arrangement of microscopic crystals and pigments that create their brilliant blue appearance — and may allow them to change color. Scientists have discovered that these nanostructures, found inside tooth-like skin scales, act like nature’s version of layered mirrors and light filters. What’s more, changes in the spacing of these layers — possibly triggered by environmental factors like water pressure — could enable the sharks to shift their color from blue to green or gold. The discovery not only unravels a biological mystery but hints at a new frontier in bio-inspired materials with applications in sustainable design and camouflage technology.

The research team at City University of Hong Kong has made a groundbreaking discovery in understanding the anatomy of blue sharks (Prionace glauca). Led by Dr. Viktoriia Kamska, they have revealed a unique nanostructure in the shark’s skin that produces its iconic blue coloration. This remarkable mechanism lies within the pulp cavities of the tooth-like scales – known as dermal denticles – that armor the shark’s skin.

The secret to the shark’s color lies in the combination of guanine crystals, which act as blue reflectors, and melanin-containing vesicles called melanosomes, which absorb other wavelengths. This collaboration between pigment (melanin) and structured material (guanine platelets of specific thickness and spacing) enhances color saturation.

When these components are packed together, they create a powerful ability to produce and change color. Dr. Kamska explains that the cells containing the crystals can be observed to see how they influence the color of the whole organism. This anatomical breakthrough was made possible using a range of imaging techniques, including fine-scale dissection, optical microscopy, electron microscopy, spectroscopy, and computational simulations.

The discovery also reveals that the shark’s trademark color is potentially mutable through tiny changes in the relative distances between layers of guanine crystals within the denticle pulp cavities. Increasing this space shifts the color into greens and golds. Dr. Kamska and her team have demonstrated that this structural mechanism of color change could be driven by environmental factors such as humidity or water pressure changes.

For example, the deeper a shark swims, the more pressure its skin is subjected to, which should darken the shark’s color to better suit its surroundings. The next step is to see how this mechanism really functions in sharks living in their natural environment.

This research has strong potential for bio-inspired engineering applications. Dr. Kamska notes that structural coloration reduces toxicity and environmental pollution compared to chemical coloration. It could be a tool to improve environmental sustainability within the manufacturing industry, especially in marine environments where dynamic blue camouflage would be useful.

As nanofabrication tools get better, this creates a playground to study how structures lead to new functions. The research has been presented at the Society for Experimental Biology Annual Conference in Antwerp, Belgium on July 9th, 2025, and is being funded by Hong Kong’s University Grants Committee and General Research Fund.
