Ever since I was younger I have had cats in my home. My parents never wanted the responsibility of owning a cat, so they rescued cats so all of us could still experience having pets. When I was growing up I lived up north where the winters were genuinely cold & all of us often had snow & ice. My childhood cats enjoyed to cuddle up next to the fireplace in the winter.I would often catch them lying down directly on top of the floor vents when all of us had the central heat on in the house. It was super cute to see, but not so cute when all of us were not as sizzling as all of us could be because the cats were blocking the vents. I observed that in the summertime up north when it started to get hot, the cats would constantly kneel on the windowsills directly in the sunlight. I wondered how they handled the heat with their fur, but they seemed to enjoy it. Now that I live in the south, I rescued two cats. They also enjoy the heat just as much as my northern felines did. I often use a heating pad to deal with cramps or back pain, & my cats will kneel directly on the heating pad. When the central air conditioning is on, which is quite often in the south, I notice that my cats search for a blanket for warmth. I also catch them cuddling together when the air conditioning is on. The cats seem to enjoy central heat over central air conditioning; Cats are the perfect pet for those who have oil furnaces in their homes.
