It's hot in February and a half. Is it normal to see snakes at home at night?

When the outside temperature is lower than 15℃, the activity of snakes begins to decrease and they are ready to hibernate. When the temperature drops to 6~8℃, the snake completely goes into hibernation. When the outside temperature is as low as 2~3 degrees Celsius, the blood flow in the snake will become very slow, and the whole body will be paralyzed and almost lose its mobility. So if the temperature is higher than 15 degrees, the snake will stop hibernating.
