They like salt, and, contrary to the general rule, it is therefore 
well occasionally to intermix some with their food; and this is an 
excellent preventive against various maladies. When linnets 
are allowed to run about, they readily feed with other birds on 
the universal paste. Some green food must occasionally be 
given them, as also sand and water, as they like to bathe and 
dust themselves. 
It is best to keep them in square cages, as they are less 
subject to giddiness in these than in round ones, and sing- 
better. They are not often allowed to range the room, as 
they are very indolent, remaining immovable in the same 
place, and running the risk of being trodden upon; but if a 
small tree or a roost be placed in a corner, they may be 
let out of the cage with safety, as they will remain perched 
there, only leaving it to eat or drink, and will sing all day 
long. 
DISEASES. 
The most common disorders of this species are consti¬ 
pation, atrophy, and epilepsy; but linnets in confinement 
will generally live from twelve to sixteen years.
