1 A cat has a total of 24 whiskers, 4 rows of whiskers on each side. The upper two rows can move independently of the bottom two rows.  Cats have 30 teeth (12 incisors, 10 premolars, 4 canines, and 4 molars), while dogs have 42. Kittens have baby teeth, which are replaced by permanent teeth around the age of 7 months.
Using current values for grass hay of around $85/ton, wheat straw should be worth about $40/ton, barley straw around $44, oat straw approximately $54, and pea straw almost $75/ton.
Both hay and straw are stacked in the form of bales in a barn, after they are dried adequately. But in comparison, straw bales are much lighter than that of hay. It is important to know the difference and to understand their use across situations and benefit from their qualities. 1. Hay is used to feed farm animals.
