a new set of antlers grow in the spring ( take three to five months to fully develop.They initially have a layer of skin, called "velvet," which is shed once the antlers become fully grown. Immature bulls may not shed their antlers for the winter, but retain them until the following spring. In extremely rare circumstances a cow moose may grow antlers. This is usually attributed to a hormone imbalance.)

dog origin
gray wolf (scientists believe they evolved from just a handful of gray wolves tamed by humans living in or near China less than 15,000 years ago. The earliest archaeological evidence of dog domestication dates back 12,000 years ago in Israel. Intensive breeding by humans over the last 500 years is responsible for the dramatic differences in appearance among modern dogs)
cat origin
studies suggests the progenitors of today's cats split from their wild counterparts more than 100,000 years ago, The earliest archaeological evidence of cat domestication dates back 9,500 years.
