כֵּיצַד אֵינוֹ שָׁוֶה לֹא לַחַיָּה וְלֹא לַבְּהֵמָה, אָסוּר מִשּׁוּם כִּלְאַיִם עִם הַחַיָּה וְעִם הַבְּהֵמָה, הַכּוֹתֵב חַיָּתוֹ וּבְהֶמְתּוֹ לִבְנוֹ, לֹא כָתַב לוֹ אֶת הַכּוֹי, אִם אָמַר הֲרֵינִי נָזִיר שֶׁזֶּה חַיָּה אוֹ בְהֵמָה, הֲרֵי הוּא נָזִיר. וּשְׁאָר כָּל דְּרָכָיו, שָׁוִים לַחַיָּה וְלַבְּהֵמָה, וְטָעוּן שְׁחִיטָה כָּזֶה וְכָזֶה, וּמְטַמֵּא מִשּׁוּם נְבֵלָה וּמִשּׁוּם אֵבֶר מִן הַחַי כָּזֶה וְכָזֶה:
How is it unlike both a wild animal and a domesticated animal? It is forbidden as <i>Kilayim</i> [the product of forbidden crossbreeding or working of certain animals with one another] with a wild animal and with a domesticated animal. If one writes that his wild animal or domesticated animal will pass to his child, he did not write over the <i>Koi</i>. If one said "I am hereby a Nazirite if it is a wild animal or a domesticated animal," one becomes a Nazirite. And in all other matters, it is similar to a wild animal and to a domesticated animal, and requires ritual slaughter like both of them, and imparts impurity as <i>Nevelah</i>, and [one is liable for eating] a limb from it [while it is still] alive like both of them.
