Cats will not choose to eat their pray within the domestic household to alleviate hunger, it is simply a choice they make to serve as a snack and there are no dietary changes required to stop this behaviour. It is completely expected that a cat will opt to chew through some of their catches and it will be worth looking out for potential harmful objects and creatures that may fall into their gaze.
While rodents in the household may be rare the appearance of insects that drawl and fly around is common.
