A Hong Kong-based Taiwanese veterinarian advised pet owners to take their cats for regular checkups to prevent the onset of heart disease, saying that the condition is difficult to detect and often causes death in cats.
Lethargy is a sign of heart problems in animals, but cats tend to be less active by nature, making it more difficult to notice when they have a problem, veterinarian Yeh Shih-ping (葉士平) said.
Regular checkups and preventative medication are advised for cats to lower their risk of heart disease, and enable early detection and treatment, he said.

In his book Animal Doctor (動物醫生), Yeh, who uses the pen name “Dr Eason,” said that heart disease is one of the biggest health threats for domesticated cats.
Heart disease is more of a risk to cats than dogs, as cats tend to sleep for most of the day and are rarely let outdoors to engage in physical activity, he said, adding that this lack of activity means that owners are more likely to overlook physiological changes in their pet and miss the early-treatment window.
Research by veterinary scientists in the US has shown that about 16 percent of domesticated cats develop heart disease, with the condition often leading to thrombosis or sudden death, he said.
The most common heart condition that cats develop is hypertrophic cardiomyopathy, in which part of the heart grows thicker and becomes less able to pump blood, he said, adding that the Maine coon, American shorthair and Persian breeds are more likely to develop this condition.
Many pet owners dismiss preventative medicine as a waste of time and simply a source of torment for cats, focusing on how frightened their cat becomes when taken to the vet, he said, adding that avoiding vet visits is a lost opportunity to prevent health problems.
With dogs, veterinarians use a stethoscope to check for a heart murmur and determine whether a dog has heart disease, but more tests are needed for cats, veterinarian Lu Tai-li (盧大立) said.
The reason is that heart murmurs are inconsistent in cats, and the presence of a murmur is not always a sign of heart disease for cats, Lu added.
About 80 percent of fatal conditions in cats are due to heart attacks, he said, adding that in most cases surgery is unnecessary.
Younger cats can get by with annual checkups and preventative shots, while those aged eight or older should have checkups every six months, Lu said.
FLU SEASON: Twenty-six severe cases were reported from Tuesday last week to Monday, including a seven-year-old girl diagnosed with influenza-associated encephalopathy Nearly 140,000 people sought medical assistance for diarrhea last week, the Centers for Disease Control (CDC) said on Tuesday. From April 7 to Saturday last week, 139,848 people sought medical help for diarrhea-related illness, a 15.7 percent increase from last week’s 120,868 reports, CDC Epidemic Intelligence Center Deputy Director Lee Chia-lin (李佳琳) said. The number of people who reported diarrhea-related illness last week was the fourth highest in the same time period over the past decade, Lee said. Over the past four weeks, 203 mass illness cases had been reported, nearly four times higher than the 54 cases documented in the same period
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
