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.
Barley crops that are harvested for silage at the soft-dough stage will yield about 20 tonnes/hectare wet forage (63% moisture) or about 7.3 tonnes/hectare dry matter (9 tons/acre wet, and 3.25 tons/acre dry). Extremely heavy crops grown on well-managed irrigated land will yield considerably more forage.
