Which version of the Bible were you reading?
1 : And the LORD spake unto Moses and to Aaron, saying unto them,
2 : Speak unto the children of Israel, saying, These are the beasts which ye shall eat among all the beasts that are on the earth.
3 : Whatsoever parteth the hoof, and is clovenfooted, and cheweth the cud, among the beasts, that shall ye eat.
4 : Nevertheless these shall ye not eat of them that chew the cud, or of them that divide the hoof: as the camel, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
5 : And the coney, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
6 : And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
7 : And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.
8 : Of their flesh shall ye not eat, and their carcase shall ye not touch; they are unclean to you.
9 : These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat.
10 : And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you:
11 : They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination.
12 : Whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you.
13: And these are they which ye shall have in abomination among the fowls; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and the ospray,
14: And the vulture, and the kite after his kind;
15:Every raven after his kind;
16:And the owl, and the night hawk, and the cuckow, and hawk after his kind,
17:And the little owl, and the cormorant, and the great owl,
18: And the swan, and the pelican, and the gier eagle,
19 : And the stork, the heron after her kind, and the lapwing, and the bat.
20 : All fowls that creep, going upon all four, shall be an abomination unto you.
21 : Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth;
Levitcus clearly identifies bats as unclean fowl. They are mammals, obviously. Genesis too refers to bats as birds and Verse 21 above refers to flying, creeping things that go on all fours. Seen any of those?
