An adult female grey squirrel (Sciurus carolinensis) is brought into your veterinary practice together with her unweaned young after their drey was, apparently, blown from a tree. The member of the public who found the squirrels only did so because her dog caught and injured the mother. A brief clinical examination found the mother to be distressed, tachypnoeic and unable to stand; a conscious radiograph identifies a vertebral fracture. The kits are all lively, keen to suckle and one of your nurses is equally keen to hand-rear them. How should you proceed?
