Will an indoor cat keep mice away?
Subsequently, one may also ask, can mice sense a cat in the house?
Mice will only build nests somewhere they feel safe and secure. Bringing a cat into your home can prevent this from happening, as mice can sense cats. This sense stems from the vomeronasal organ inside a mouse. In many respects, it's an enhanced sense of smell.
Similarly, will Mice Stay away if you have cats?
If they're smart, yes. Mice know cats are in your home because they can smell their predators. The mere whiff of cat urine and litter is often enough to scare the mice away.
Under the right circumstances, almost any cat will kill a mouse. However, some cats seem to live for the hunt while others prefer to wait for the occasional mouse to stumble directly into their food bowls.
