Please keep in mind that your cat may struggle with frost and snow now, as it becomes impossible to bury their business in the frozen ground as they’d prefer.
In these temperatures, cats that normally manage their needs outdoors are now desperately searching for a spot inside the house where they can quietly take care of business.
So, even for outdoor-loving cats, make sure to provide an appropriate litter box indoors—at least during the winter, though ideally all year round.
