Nope. Satan is not a mammal Only mammals have blood.

Satan is a spirit creature.

God says that life is in the blood. When we lose blood we die, so it might be helpful to find out what Satan could be? In Ezekiel 28:14 he is referred to as a Cherub, people often think this verse is merely about a king, like in Isaiah, when this verse refers to a man and a cherub, like the Genesis story isn't simply about a talking snake, nachash means serpent, shining one, also one that whispers. In the Book of Enoch there are two leading fallen Watchers Azazel often assimilated with Lucifer or lumiel, the light bearer, and Semyaza who held the rank of seraphim which comes from "burning one/serpent." What's also interesting is that fire doesn't always mean the same as we know fire Exodus 3:2 The angel of the LORD appeared to him in a blazing fire from the midst of a bush; and he looked, and behold, the bush was burning with fire, yet the bush was not consumed. God is also often equated with fire.. Exodus 13:21 The LORD was going before them in a pillar of cloud by day to lead them on the way, and in a pillar of fire by night to give them light, that they might travel by day and by night. Leviticus 9:24 Then fire came out from before the LORD and consumed the burnt offering and the portions of fat on the altar; and when all the people saw it, they shouted and fell on their faces. Numbers 11:1 Now the people became like those who complain of adversity in the hearing of the LORD; and when the LORD heard it, His anger was kindled, and the fire of the LORD burned among them and consumed some of the outskirts of the camp. Numbers 16:35 Fire also came forth from the LORD and consumed the two hundred and fifty men who were offering the incense. 2 Kings 2:11 As they were going along and talking, behold, there appeared a chariot of fire and horses of fire which separated the two of them. And Elijah went up by a whirlwind to heaven. Daniel 3:25 He said, "Look! I see four men loosed and walking about in the midst of the fire without harm, and the appearance of the fourth is like a son of the gods!" Hebrews 12:29 for our God is a consuming fire.

Just like God is a Spirit, Satan is also a spirit. He is the prince of the power of the air. (Ephesians 2:2) The chance of Satan having fleshy blood: he can inhabit humans and animals. (Mark 5:1–13)
