Which of the following examples of species associations is not correct?
Horses and cats are more sensitive to opioids than dogs and ruminants.
The use of anticholinergics is recommended in ruminants to avoid airway occlusion
Horses may fracture limbs during anesthetic recovery and thus require special attention during the recovery period
Large animals are prone to respiratory depression and dependent atelectasis and thus often require ventilatory support
