A study published in Nature Communications found that cats are one of the biggest threats to endangered species in the US. According to the study our adorable fluffy kittens quickly grow into predators and so far they have killed up to 3.7 billion birds and between 6.9 and 20.7 billion mammals.
They emphasize that “un-owned cats” are the culprits here. Though the numbers may be shocking, their discovery isn’t particularly startling. Un-owned cats have already been implicated in 33 modern bird, mammal, and reptile extinctions, write the researchers in Nature Communications.
The most dangerous felines are stray and feral cats but the study also blamed pet cats for threatening the US wildlife. The authors have put the blame also on cat owners arguing they should do more to curb their felines’ killer instinct. Pet cats are believed to be responsabile for the extinction of 33 species. The animals threatened the most by cats are mice,shrews, voles, squirrels and rabbits.
