A study published in PLOS One reveals that cats' purring behavior is linked to genetic variation, specifically the short-type androgen receptor gene. Cats with this gene exhibit higher owner-assessed purring scores than those with the long-type gene.
A study published in PLOS One found that domestic cats can discriminate between familiar and unfamiliar humans based on their odor. Cats spend longer sniffing the odor of a stranger than that of their owner, suggesting they can identify human scent patterns.
The book argues that domestication began as a natural process, with humans unintentionally influencing the evolution of plants and animals through habitat creation. This perspective has significant implications for conservation initiatives today.
New research by the University of Bristol and Cats Protection reveals that road traffic accidents are the leading cause of death in UK pet cats under 8 years old. The study found that younger cats are at higher risk of death due to RTAs, while older cats are more likely to die from disease-related causes.
A small study found 19 types of microplastic particles in cat placentas and fetuses during early pregnancy. The researchers suggest that microplastics may accumulate in cat placentas and potentially impact fetal health, highlighting the need for limits on plastic use and mitigation strategies.
A Danish study found that rural cat owners are increasingly managing their cats similarly to urban owners, leading to fewer unwanted kittens. The change reflects a growing human attachment to owned cats and a diminishing divide between rural and urban life.
Researchers developed a machine learning model that predicts the presence of animal feeding operations with high accuracy, filling a data gap crucial for managing their environmental impacts. The model uses predictors such as surface temperature and phosphorus levels to identify locations without relying on aerial images.
