Salt licks are a natural deposit of exposed salt or a block of salt often with added minerals or vitamins, set out for animals such as cattle, sheep, horses, or deer to lick. Natural licks are common, and they provide the biometals (sodium, calcium, iron, phosphorus, zinc, and trace elements) required in the springtime for bone, muscle and other growth in deer and other wildlife, such as moose, elephants, tapirs, cattle, woodchucks, domestic sheep, fox squirrels, mountain goats and porcupines. Such licks are especially important in ecosystems with poor general availability of nutrients.
So can chinchillas eat salt licks?
Unfortunately they can’t at all. The saltiness is just too much for them and they just can’t handle it. They should not be eating salt licks at all.
