For her entire life, my cat has been indoors and as best I can tell has no desire to go outside. However, she still regularly wants to go to certain parts of the house, which could potentially be dangerous to her from an environmental perspective.
Specifically, she likes to follow me into the laundry room and garage. Assuming the temperature outside is 32°F (0°C), then the laundry room might be only 50°F (10°C). Or worse, she follows me into the garage which might be only 37°F (3°C).
I have attempted to bodyblock her from even entering these areas, but this isn't always feasible when carrying things. Furthermore, if I attempt to pick her up and put her back into the house proper, she will occasionally run away from me and hide somewhere that's risky to try and get her from (i.e. I don't want her running across the tool bench in the garage and potentially knocking things down). She's not averse to being picked up, so I take the fleeing to mean that she really wants to explore the area and don't bother chasing.
Given the aforementioned temperatures, the doors to these rooms generally remain closed (if relevant, we keep the thermostat set around 62°F (17°C) at night). So far, my methods have been to leave her be out there until she starts meowing at the door to come inside. My hope being that she'd realize that whenever she goes out here, she gets stuck in place without heat, food, water, companionship, or a place to poop. However, after 2 years living in this house, her desire to be in these places hasn't dissipated.
Given the risk of injury due to exposure, is there a better way to persuade her to stay inside?
