ח שְׁמוֹנָה שְׁרָצִים הָאֲמוּרִים בַּתּוֹרָה, הַצָּדָן חַיָּב וְהַחוֹבֵל בָּהֶם, אַף עַל פִּי שֶׁלֹּא יָצָא מֵהֶם דָּם אֶלָּא נִצְרַר תַּחַת הָעוֹר, חַיָּב; וּשְׁאָר שְׁרָצִים, אֵינוֹ חַיָּב הַחוֹבֵל בָּהֶם אֶלָּא אִם כֵּן יָצָא מֵהֶם דָּם, וְהַצָּדָן לְצֹרֶךְ, חַיָּב; שֶׁלֹּא לְצֹרֶךְ, אוֹ סְתָם, פָּטוּר אֲבָל אָסוּר, וּלְהָרַמְבָּ"ם חַיָּב.
8 Regarding the Eight Sheratzim mentioned in the Torah {a rat, a mouse, a Tzov, a ferret, hedgehog, chameleon, lizard, snail and mole}, one who captures or bruises them is liable even though they did not bleed externally and the blood only accumulated beneath the skin. With regard to other reptiles, one is liable for beating them, only if there was external bleeding. One who captures them for a purpose is liable and one who captures them for no purpose or for no specific reason is exempt but forbidden to do so. The Rambam holds that one is liable.
