Care and feeding
The basis of the Mini Rex’s diet is good-quality hay available at all times, supplemented with fresh vegetables and a small amount of specific pellets; hay is also essential for the correct wear of its teeth. It needs spacious, clean housing free of draughts and stress. Watch that it eats and passes droppings normally: a rabbit that stops eating is a veterinary emergency.
Exercise and stimulation
The Mini Rex needs space to move and jump every day outside its enclosure, in a safe, supervised area. Tunnels, chew toys and hiding places keep it active and happy and help prevent boredom and behavioural problems.
