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 Degree Day is simply a unit for measuring how cold (or hot) it has been over a 24 hour period. Whenever the average (or mean) temperature is below 65Â°, you have a Degree Day. For example, if during a 24 hour period the high outdoor temperature was 70 degrees and the low was 50 degrees, then the average temperature for that day was 60 degrees - halfway between 70 and 50 degrees. This is 5 degrees less than the base temperature of 65Â°.
