1970s–1980s Robinson ended her breeding program in the 1970s. Sigyn Lund (Sig Tim Hil Cattery) a Florida Burmese breeder, purchased some of Robinson's kittens and took on the "Foreign Longhair" breeding program. The New York origin was not well known to the public at the time. Because of Lund's reputation as a Burmese breeder, It has been speculated that the Chantilly was a long haired Burmese. A change in the breed's name was requested by judges, because they felt the breed's current name "Foreign Longhair" was too general; the name "Mahogany" was suggested, but Lund changed the breed-name from "Foreign-Longhair" to "Tiffany" for the latter's feeling of elegance and class. Lund promoted the breed under "Tiffany". The ACA dropped the "Tiffany" from recognition, their reason being its rarity. As a result, all breed representatives registered under the Lund (Sig Tim Hil Cattery) name became unregistered and lost their pedigree status. After this event, the breed continued to be advertised as "Burmese". At one point, in an informal phone interview, Sig Tim Hil Cattery supplied information to researcher Joan Bernstein regarding these chocolate cats. This interview resulted in a publication of information, again suggesting the possibility they were the product of UK crosses between Burmese and Himalayans (a Persian/Siamese cross). This information was posted in Harper's Illustrated Handbook of Cats. In The Ultimate Cat Book by David Taylor in 1989, the Tiffany's history was also described as "produced from crossing Burmese cats with Persians". The false advertisement and the phone interview could explain the tie to the Burmese in these books. The confusion led the breed to near-extinction. Chantillys and Canadian/American teamwork (1980s–1990s) Around the same time Robinson and Lund were developing the "Tiffany" in the United States, a Canadian acreage owner was surprised by a cat who appeared at his home in 1973. She was a long-haired, semi-foreign, chocolate, gold-eyed feline of unknown ancestry who gave birth to a litter of kittens. Once again these kittens were carbon copies of their mother, an experience shared by Robinson with the cats in her breeding program. Offspring of these were rescued by Canadian breeders in order to re-establish the "Tiffany" breed in North America with a cooperative effort with Robinson and Lund. One major advocate of the Chantilly was Tracy Oraas, who began her involvement with the breed in 1988 when she responded to a classified ad advertising "chocolate kittens." Oraas got
