No. Mammals do not have scales. Mammals have skin and hair. Some mammals feature scaly skin on some of their body parts such as their legs, but these are by no means scales. In the case of some animals, what may appear to be scales are in fact modified hairs. The pangolin is an example of this. Its scaly plates, like the scaly skin of reptiles, are made of keratin. Note that reptiles also do not have scales - just scaly skin. The only vertebrates with true scales are fish.
