наверное животное не вылизывается, выглядит неопрятно.
Ungroomed, otherwise AN - значт, что если клеточка не отмечена, значит выглядят обычно.

AN - Внешний вид в норме
U - Шерсть взъерошена, в ином случае: AN (Внешний вид в норме)

подопытных животных наблюдались гнойные абсцессы, расчесы на морде и по
туловищу, шерсть была взъерошенной, "

Personal grooming (also called preening) is the art of cleaning, grooming, and maintaining parts of the body. It is a species-typical behavior.
In animals
Individual animals regularly clean themselves and put their fur, feathers or other skin coverings in good order. This activity is known as personal grooming, a form of hygiene. Extracting foreign objects such as insects, leaves, dirt, twigs and parasites are all forms of grooming. Among animals, birds spend considerable time preening their feathers. This is done to remove ectoparasites, keep them in good aerodynamic condition, and waterproof them. To do that, they use the preen oil secreted by the uropygial gland, the dust of down feathers, or other means such as dust-bathing or anting. During oil spills, animal conservationists that rescue penguins sometimes dress them in knitted sweaters to stop them from preening and thereby ingesting the mineral oil which is poisonous. Monkeys may also pick out nits from their fur or scratch their rears to keep themselves clean. Cats are well known for their extensive grooming. One reason advanced for such grooming is to remove all traces of blood and other matter so as to not alert prey with the scent. Cats grooIn animals[edit]

Этологический анализ груминга при стрессе.
Исследование поведения лабораторных грызунов является удобным методом при скрининге различных психотропных веществ.
