SB 5.26.13
yas tv iha va ugrah pasun paksino va pranata uparandhayati tam apakarunam purusadair api vigarhitam amutra yamanucarah kumbhipake tapta-taile uparandhayanti.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
For the maintenance of their bodies and the satisfaction of their tongues, cruel persons cook poor animals and birds alive. Such persons are condemned even by man-eaters. In their next lives they are carried by the Yamadutas to the hell known as Kumbhipaka, where they are cooked in boiling oil.
