Tea eggs contain caffeine and theophylline, which are dangerous for pets, as they can lead to severe muscle contractions, epilepsy, faintness or even death, a veterinarian said.
Caffeine and theophylline are methylxanthines and overconsumption can lead to increased cellular calcium concentration, which can cause intense muscle spasms, Taipei-based Primo Animal Hospital dean Chang Yang-chung (張洋崇) said on May 19, in response to a post on Facebook about a dog that was hospitalized after its owner fed it tea eggs.
Pets begin exhibiting signs of methylxanthine poisoning one to four hours after consuming the substance, with symptoms including spasms, vomiting, diarrhea, palpitations, urine leakage, high body temperature, seizures and faintness, Chang said, adding that poisoning can be fatal.
Tea bags and implements should be stored out of reach of pets to prevent them from accidentally consuming large amounts of tea leaves, he said.
Pets should be immediately taken to a veterinary clinic should they eat tea leaves, he added.
Separately on May 14, Taiwan Society for the Prevention of Cruelty to Animals researcher Chen Ting-yu (陳庭毓) drew attention to stereotypic behaviors of pets that receive too little attention from their owners.
Such behaviors — including pacing, spinning in circles, unresponsiveness when called and constant biting or licking of the body despite having no ailment — can be repetitive and seemingly aimless, and are more commonly observed in animals kept in zoos or laboratories than in wild animals, Chen said.
Stereotypies are not treatable and can result in physical harm to pets, such as injuries to limbs due to continuous pacing, skin damage or bacterial infections resulting from biting and licking, she said.
Stereotypies indicate that pets are stressed, lack environmental stimuli and not receiving sufficient care, making them lose their sense of existential purpose, which they compensate for by “seeking fun for themselves,” such as feeling pain by biting themselves, as a way to feel alive, she added.
While stereotypies are irreversible, there are ways to alleviate them, Chen said, adding that people must take the initiative and take incremental steps to interact more with their pets.
Taking pets out for a walk, playing games and talking to them are all goods ways to show them that they are valued and alleviate their stereotypies, she said.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
A white king snake that frightened passengers and caused a stir on a Taipei MRT train on Friday evening has been claimed by its owner, who would be fined, Taipei Rapid Transit Corp (TRTC) said yesterday. A person on Threads posted that he thought he was lucky to find an empty row of seats on Friday after boarding a train on the Bannan (Blue) Line, only to spot a white snake with black stripes after sitting down. Startled, he jumped up, he wrote, describing the encounter as “terrifying.” “Taipei’s rat control plan: Release snakes on the metro,” one person wrote in reply, referring
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
Taiwan’s two cases of hantavirus so far this year are on par with previous years’ case numbers, and the government is coordinating rat extermination work, so there should not be any outbreaks, Centers for Disease Control (CDC) Director-General Philip Lo (羅一鈞) said today in an interview with the Liberty Times (the Taipei Times’ sister newspaper). An increase in rat sightings in Taipei and New Taipei City has raised concerns about the spread of hantavirus, as rats can carry the disease. In January, a man in his 70s who lived in Taipei’s Daan District (大安) tested positive posthumously for hantavirus, Taiwan’s
