Golden Guernsey: The Golden Guernsey is a rare breed of goat from the Bailiwick of Guernsey on the Channel Islands.  They were first brought to Great Britain by Rudi Sweg in 1965 and a sub-breed has evolved known as the "British Guernsey".

Persian cat: The Persian cat (Persian: گربه ایرانی "Gorbe Irâni") is a long-haired breed of cat characterized by its round face and short muzzle.  It is also known as the "Persian Longhair".  In the Middle East they are widely known as "Iranian" and in Iran they are known as "Shirazi".  The first documented ancestors of the Persian were imported into Italy from Iran (Persia) around 1620.  The exact history of the Persian cat does seem to be a bit of a mystery but many of these long-haired cats were seen in hieroglyphics.  The story has it that these long-haired cats were then imported into Europe as their popularity grew and breeding took place in Italy and France.

Kashmir cat: The Kashmir type of cat is not recognized as its own breed by many cat fancier and breeder organizations, being usually more of a label of a coat type: semi-long-haired to long-haired, and grey or brown.  The variety is essentially a solid-colored Himalayan, and has been the subject of much disagreement.  They were originally born in litters of Himalayans and have been bred to each other to create pure coats with rich lilac to chocolate colors.

Laticauda sheep: The Laticauda is a breed of domestic sheep from Campania and Calabria, in southern Italy.  It is a fat-tailed breed, which gives rise to the name Laticauda, "broad-tailed".  It is raised mainly in its area of origin in the provinces of Avellino, Benevento and Caserta, but is also found in the provinces of Cosenza, Matera and Naples.  Like the Barbaresca breed of Sicily, it appears to result from the hybridisation of local breeds with Barbary (or Barbarin) sheep of Maghrebi origin.  It has been suggested that these were first brought to the area by the Bourbon king Charles VII of Naples.

American Bobtail: The American Bobtail is an uncommon breed of domestic cat which was developed in the late 1960s.  It is most notable for its stubby "bobbed" tail about one-third to one-half the length of a normal cat's tail.  This is the result of a cat body type genetic mutation affecting the tail development, similar to that of a Manx cat.  The breed is not related to the Japanese Bobtail despite the similar name and physical type—the breeding programs are entirely unrelated, and the genetic mutation causing the bobbed tail are known to be different because the mutation causing the American Bobtail's tail is dominant, whereas the Japanese Bobtail tail mutation is recessive.

Luna the Fashion Kitty: Luna the Fashion Kitty is a Himalayan cat with a following on the Internet that centers on a Facebook page where she shares her outfits each day.  She also shares information about cat grooming and cat rescue info, specifically focusing on the Persian and Himalayan breeds.  Her Facebook page essentially functions as a social media community for cat lovers and fashion fans.

Homeward Bound II: Lost in San Francisco: Homeward Bound II: Lost in San Francisco is a 1996 American adventure comedy film and a sequel to the 1993 film "".  Directed by David R. Ellis, the film features the three animals from the first film, Shadow the Golden Retriever (voiced by Ralph Waite, replacing Don Ameche, who died in 1993), Sassy the Himalayan cat (Sally Field), and Chance the American Bulldog (Michael J. Fox).  It also features the voice work of Sinbad, Carla Gugino, Tisha Campbell-Martin, Stephen Tobolowsky, Jon Polito, Adam Goldberg, Al Michaels, Tommy Lasorda, and Bob Uecker.

Norwegian Forest cat: The Norwegian Forest cat (Norwegian: Norsk skogkatt or Norsk skaukatt ) is a breed of domestic cat originating in Northern Europe.  This natural breed is adapted to a very cold climate, with top coat of glossy, long, water-shedding hairs and a woolly undercoat for insulation.  Although this is uncertain, the breed's ancestors may have been a landrace of short-haired cats brought to Norway by the Vikings around 1000 AD, who may also have brought with them long-haired cats, like those ancestral to the modern Siberian and Turkish Angora breeds.  During World War II, the breed became nearly extinct until efforts by the Norwegian Forest Cat Club helped the breed by creating an official breeding program.  It was registered as a breed with the European Fédération Internationale Féline in the 1970s, when a local cat fancier, Carl-Fredrik Nordane, took notice of the breed and made efforts to register it.  Currently, the Norwegian Forest breed is very popular in Norway, Sweden, Iceland and France.

Himalayan cat: The Himalayan (a.k.a. Himalayan Persian, or Colourpoint Persian as it is commonly referred to in Europe), is a breed or sub-breed of long-haired cat identical in type to the Persian, with the exception of its blue eyes and its point colouration, which were derived from crossing the Persian with the Siamese.

Dartmoor longhouse: The Dartmoor longhouse is a type of traditional stone-built home, typically found on the high ground of Dartmoor, in Devon, England and belonging to a wider tradition of combining human residences with those of livestock (cattle or sheep) under a single roof specific to western Britain; Wales, Cornwall and Devon, where they are more usually referred to simply as 'longhouses' and in general housebarns.  The earliest are thought to have been built in the 13th century, and they continued to be constructed throughout the mediaeval period and into the Early Modern, using local granite or other stone.  Longhouse near Carreg Cennen Castle in Wales is dated to 11th century.  Many longhouses are still inhabited today (although adapted over the centuries), while others have been converted into farm buildings.  Forms of longhouses identical to those on Dartmoor are found in Cornwall, particularly on Bodmin Moor and in Wales where they are commonly called "tyddyn" meaning 'homestead', or specifically "Ty Hir" meaning 'long-house' in the Welsh language.  A near identical type called the "(Maison) Longère" can also be found in northwestern (Brittany, Normandy) and central France.
