1 In general, the cat's posture should be fairly straight instead of having the cat sag against your chest, with its head and neck craned downward. 2  This is uncomfortable for the cat and may cause it to struggle and scratch you. 3  You should always pick up a cat with its head above its body.f you want to pick up a cat, then you should first approach it in a way that lets it know you're coming. This can mean talking to it softly, letting it see you, or just making your presence known in some way.
Heating degree days, or HDD, are a measure of how much (in degrees), and for how long (in days), outside air temperature was lower than a specific base temperature (or balance point). They are used for calculations relating to the energy consumption required to heat buildings.
A temperature of 18 Â°C indoors corresponds to an outside temperature of about 15.5 Â°C. If the air temperature outside is 1 Â°C below 15.5 Â°C, then heating is required to maintain a temperature of about 18 Â°C. If the outside temperature is 1 Â°C below the average temperature it is accounted as 1 degree-day. The sum of the degree days over periods such as a month or an entire heating season is used in calculating the amount of heating required for a building. Degree Days are also used to estimate air conditioning usage during the warm season.
