 If this suggestion is rejected, and we allow that some animals, at least, should be included within the scope of justice, we can then ask about the form that justice should take in their cases. Using the distinction drawn in 2.4 above, it appears that justice for animals must be non-comparative. For example, we might attribute rights to the animals over whom we exercise power – rights against cruel treatment, and rights to food and shelter, for instance. This would involve using a sufficiency principle to determine what animals are owed as a matter of justice. It is much less plausible to think that comparative principles might apply, such that giving special treats to one cat but not another could count as an injustice.
