Chronic Diseases Surge in Pets, Livestock, and Wildlife Globally

Chronic diseases, such as obesity, diabetes, and kidney disease, are becoming a growing issue among animals, from pets to wildlife. A recent study highlights that these conditions are often overlooked, despite their rising impact. Researchers warn that without better monitoring, the problem could worsen across species.

The study reveals that companion animals, such as dogs and cats, increasingly suffer from obesity, diabetes, and kidney disease. Livestock, including cows and pigs, also face metabolic disorders, osteoarthritis, and fatty liver disease. These trends mirror human health challenges, with diet, ageing, and poor welfare conditions playing key roles.

Wildlife is not spared. Beluga whales and California sea lions have been diagnosed with cancer, while raccoons show high blood sugar levels. Green sea turtles battle fibropapillomatosis, a tumour-causing disease. In Europe, isolated reports note rising cases of cancer and metabolic disorders in seals and deer, linked to habitat loss and pollution. Similar patterns appear in North America and Asia, though no comprehensive global data exists for comparison.

Experts point to multiple causes behind these diseases: genetics, environmental pollutants, and climate change. The study stresses that chronic illnesses could further strain already vulnerable wildlife populations. Without proper tracking, the full scale of the problem remains unclear.

Researchers suggest that conservation efforts should address chronic diseases as a key stressor. Measures like pollution control, habitat restoration, and climate adaptation could help improve animal health across ecosystems.

The findings highlight a need for better monitoring of chronic diseases in animals. Without action, these conditions may continue to spread, affecting pets, livestock, and wildlife alike. Conservation strategies now face the challenge of integrating health risks into long-term planning.
