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.
Also, hay is typically priced by weight when selling in larger quantities, and the weight of a bale will vary due to how tightly it's baled and the moisture content of the hay. That said, my bales (alfalfa) varied between 1,300 and 1,600 pounds, and sold for anywhere from $50 to $95.
