Near the Furnace or Heater
One other common thread in cat hiding places is the animal’s desire to seek warmth. This is something owners will commonly see during the winter, but it’s definitely not exclusive to December, January, and February in northern states.
One of your home’s warmest spots is the furnace, which is obviously an area fraught with danger for your cat. Keep it inaccessible by closing the basement or furnace room door at all times. If that’s not possible for whatever reason, use a gate that you know your cat can’t jump.
On the off chance that your cat gets in there, it’s important to find ways to strongly dissuade him from wanting to go in there again. However, as Koski explains, there’s some risk in the way you associate negative consequences with a hiding place.“To deter cats, do not startle them out of a hiding spot, yell at them, or squirt them with water,” she says. “This can only create fear and damage your relationship with the cat.” Instead, use the scents mentioned earlier, like peppermint and citrus, which might make the area unpleasant. Koski also says you can place a vinyl carpet runner in the area with the nubs pointed up. “They’ll find it very uncomfortable to walk on.”
