Wolves as pets and working animals
Generally speaking, on the basis of their experience, tame wolves are strictly "one-man dogs". They may be confiding and playful with the man who raised them, or even with his whole family, if fed and cared for by them, but they are suspicious and timid in the presence of strangers. They invariably retain certain reactions of wolf nature, as for instance, an incorrigible desire to kill chickens or other small livestock whenever opportunity arises.
Domestic rabbit
Rabbits may be kept as small house pets and "rabbit-proofed" spaces reduce the risks associated with their intrinsic need to chew. Rabbits are easily litter box trained and a rabbit that lives indoors may be less exposed to the dangers of predators, parasites, diseases, adverse weather, and pesticides, which in turn increases their lifespan. Rabbits are often compatible with others of their kind, or with birds or guinea pigs, but opinion differs regarding the dangers of housing different species together. Some people consider rabbits a pocket pet.
Keeping a rabbit as a house companion was popularised by Sandy Crook in her 1981 book "Your French Lop". In 1983, at the American Family Pet Show in Anaheim, California (attended by 35,000), Crook presented her personal experiences living with an indoor rabbit as evidence of a human-rabbit bond. In the late 1980s, it became more common to litter box train a rabbit and keep it indoors, after the publication of Marinell Harriman's "House Rabbit Handbook: How to Live with an Urban Rabbit" in 1985. (The book's fifth edition was published in 2013.)
