Evacuation is always somewhat chaotic, and it may turn out there isn't really "room" for all the humanoids, either, despite all the ships no doubt possessing plenty of surplus evacuation capacity. Lifeboats may turn out to be out of reach, out of order, too hotly contested, or inaccessible to the too badly wounded.
However, the ships appear capable of carrying a lot more personnel/passengers than they regularly are seen carrying. Evacuation capacity would more or less have to be scaled for the theoretical carrying capacity rather than the practical one, meaning the horses and wolfpacks would again have plenty of room - in theory. In practice, some people and animals are likely to be left behind for various reasons, which may be actually more pressing in the case of people than animals (because people may have valid reasons to remain behind) but are more likely to actualize with animals (because they are too stupid to evacuate on their own).
A clever designer might create evacuation systems that are intuitively easy to operate even for animals, because that would help panicking and wounded and otherwise confused people, too. Alas, the panic reaction of a human is likely to differ from that of a cat. But it might still pay off to build lifeboat entry hatches under beds!
(Also, not a targ. End of story.)
