Choose the type. Then check the facts.
Mini Highland, micro mini, Highpark, heifer, bull, and breeding-pair descriptions answer different questions. Some describe ancestry or appearance; others describe sex, a size claim, or how animals are offered together. None by itself establishes health, adult size, handling, or suitability.
Ask for identification, documented age, known ancestry, dated measurements, and relevant health records. Review the actual individual with your veterinarian rather than assuming every animal in a category is alike.
