‘“And I will make a covenant of peace with them, and I will rid the land of vicious wild beasts..
‘“And I will conclude with them a covenant of peace, and I shall certainly cause the injurious wild beast to cease out of the land,..
First off, as far as what the Scripture states and what the WTS artist painted, their is no basis to paint this cat in the tree. The Scripture states that Jehovah will rid/cause to cease the wild beasts from out of the land. So that cat (wild beast) should not even be depicted in the picture.
Second, that context of that verse is not talking about actual animals as being the wild beasts, it is referring to men, the evil shepherds that do harm, that they will no longer be there. (be gotten rid of/cease from out of the land)

Likewise:
Isaiah 35:8 And a highway will be there, Yes, a way called the Way of Holiness. The unclean one will not travel on it. It is reserved for the one walking on the way; No one foolish will stray onto it. 9 No lion will be there, And no vicious wild beasts will come on it. They will not be found there; Only the repurchased ones will walk there.
(Matthew) Be
on the watch for the false prophets who come to you in sheep’s covering, but
inside they are ravenous wolves.
(Acts) I
know that after my going away oppressive wolves will enter in among you
