Richard why do you think only 1 animal can be bonded at a time?
After reading the Animal Bond now, it reads "... a single animal with which he is currently interacting." and nothing else.
This seems to suggest you could bond with more than one, activating only one of those via maneuver. But this would need to be addressed via role play so as not make it OP like with Squad Rules etc.
Same as maybe having a droid menagerie but now the animals become too unruly when there are too much of them and the obvious hassle to flying from place to place with such a zoo.
I am also basing this on the wording of the Menace talent in savage spirits saying "... any suitably threatening creature linked through the animal bond talent". This and the wording on the animal companions rules suggests to me the possibility of more than one bonded animal otherwise they could have simply said "the bonded animal" or other statements referring to a singular companion.
They probably left it open for group interpretation and different table uses.
