Whether use is to be found in irrational animals?

Objections

Objection 1 : It would seem that use is to be found in irrational animals. For it is better to enjoy than to use, because, as Augustine says (De Trin. x, 10): "We use things by referring them to something else which we are to enjoy." But enjoyment is to be found in irrational animals, as stated above (Question [11], Article [2]). Much more, therefore, is it possible for them to use.
Objection 2 : Further, to apply the members to action is to use them. But irrational animals apply their members to action; for instance, their feet, to walk; their horns, to strike. Therefore it is possible for irrational animals to use.
