Animals have no rights 🫡
Rights are actions that the grantor makes known the he/she will allow when taken by the grantee. But also, rights are actions that the grantee demands of others to not be interefered upon when he/she takes them. I think nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m pointing out the latter doesn't clobber the former.
I don't think of anybody as a "higher power" so I think recognition of rights is a pairwise thing.
Principals on the grantor side are ideally are just humans (or AI or intelligent animals that have the capability to participate as principles) whereas grantees could be dumb animals (we give rights to chickens). Too often grantors are broadly conceived of as groups (governments, etc) and in order to understand other people you need to borrow their ill conceptions.
