The domestic cat is an invasive species in many different countries it is estimated that feral and outside cats kill over a billion small mammals and songbirds each year the hunting habits of these cats is hypothesized to be one of the largest contributions to the rapidly decreasing number of songbirds in North America some songbirds like the North American barn swallow seem to be less affected by the outside feral cat honey a researcher located in Oklahoma Dr Charles Brown has recorded evidence of swallows adapting to have shorter Wing over the past 30 years barn swallows are now one of the few song birds that have slightly increasing wild population

numbers, thanks to their ability to adapt to the threat of feral cats. Despite this adaptation, the impact of feral cats on other songbird populations remains a critical issue for conservation efforts.

Efforts to control the population of feral cats, such as trap-neuter-release programs, have been implemented in some areas to mitigate their impact on local wildlife. However, the effectiveness of these programs varies, and the issue of feral cats preying on native wildlife continues to be a concern for conservationists.

In conclusion, the hunting habits of feral and outside cats have a significant impact on local wildlife populations, particularly small mammals and songbirds. Conservation efforts are needed to address this issue and protect vulnerable species from the threat of predation by invasive cats.
