In the 20th century, most U.S. states outlawed the keeping of wild animals as part of their efforts to stem the spread of rabies. Only about one-third of states continued to allow domestic skunks. In the 1990s, skunk enthusiasts began establishing mailing lists and organized for skunk law reform. In the 2000s, similar initiatives took place in Canada.

Black-and-white skunks are illegal in Canada.
Pet skunks kept for any reason are banned in the Canadian province of Ontario, as of 1999.
In Canada, Mike Freeman of Freeman's Exotic Skunks was ordered in 1999 by the Ontario Ministry of Natural Resources to destroy his entire stock of 100 adult and 700 baby skunks. Although the agency had approved his farm in 1997, the 1998 Fish and Wildlife Act outlawed breeding. Natural Resources Minister John Snobelen ultimately gave him six months to sell or give away the animals in the U.S., saying, "No one wants to see these animals euthanized and that won't have to happen".[57]
Skunks as Pets Canada leader Vivianne Chernoff and other activists subsequently persuaded the Canadian Food Inspection Agency to legalize importation of pen-bred skunks. Although NRC does not recognize the CFIA laws, the CFIA assured Chernoff that NRC cannot confiscate a micro-chipped skunk whose legality is documented with import papers and a health certificate. In 2004, Canadian activists were working on having a tear duct rabies test legalized for skunks.
