In most of the world the Rex, like other domestic rabbits, is legal to keep without special permission, but local rules vary and should always be checked before acquiring an animal. This page is informational only and is not legal advice; the universal site disclaimer applies, and readers should confirm current requirements with their own jurisdiction.
Some regions impose notable restrictions. In Queensland, Australia, for example, keeping domestic rabbits as pets is generally prohibited except in limited circumstances, reflecting concerns about feral rabbit populations. Other areas may classify rabbits as livestock rather than pets, which can affect where and how many may be kept.
Because rules can hinge on whether a rabbit is treated as a companion animal or as livestock, prospective owners should review municipal ordinances, agricultural codes, and any permit requirements that apply to their specific location.
