A licensee shall not sell, exchange, or adopt any animal if the animal is at an age at which doing so would be detrimental to the animal's health or well-being. No puppy or kitten may be sold, exchanged, or adopted until the animal is at least eight weeks of age and has been weaned, which shall mean eating solid food and not nursing, for at least five days.
For the purposes of this regulation, weight and other factors may be used to approximate the age of an animal of unknown age.
