<human>:  Are Sable's a good choice of Mustelidae to weigh down a scale?
<bot>: No, Sable's are not a good choice of Mustelidae to weigh down a scale. Mustelidae is the scientific designation for animals that share similarities including polecats, sables, and ferrets. Polecats weigh between 2.2 and 3.3 pounds. Sable's weigh around 2.4 pounds. So Sable's are not a good choice.
