The ferret
Playful, clever, endearing — but demanding
The ferret is a small carnivore domesticated since ancient times, full of energy and very curious. It sleeps a lot but needs several hours out of its cage and at play every day. It is the emblem animal of the Au Furet practice.

Its essential needs
- Several hours of supervised time out of the cage every day, in a secure room (ferrets squeeze in everywhere).
- A strictly carnivorous diet: very high quality food made specifically for ferrets, or kitten food; never plant-based.
- A spacious cage on several levels with a hammock, and ideally a companion of the same species.
- A cool temperature: the ferret copes very badly with heat (heatstroke from 28–30 °C).
Key health points
- Canine distemper is a highly contagious virus, with no treatment and almost always fatal in the ferret: vaccination is the only real way to protect him, even if he never goes outside.
- A female ferret left in season without being mated stays in season, and the excess hormones eventually exhaust her bone marrow — she no longer makes enough blood cells, which can kill her. Neutering or a hormone implant avoids this risk; in the male, it also reduces the smell and the fighting.
- As he ages, the ferret often develops two hormonal diseases. A small tumour of the pancreas makes blood sugar drop (an insulinoma): he becomes wobbly in the hind end, trembles, or stares into space for a few seconds. Two glands located near the kidneys produce too many hormones (adrenal gland disease): the hair falls out symmetrically, often starting with the tail. See a vet at the first signs — caught early, these diseases are well managed.
In Switzerland: no permit required No permit required, but keeping is subject to the TSchV requirements on living conditions: minimum space, social contact, and appropriate feeding and care. Legal framework in detail →
A word from the Au Furet practice A ferret that ‘dances’ with an arched back is not being aggressive: it is an invitation to play.
