After describing about five groups of unclean animals/creatures in Leviticus 11 it seems only the swarming creatures have the effect of defiling other vessels like stoves,ovens and pots besides human beings.
These "extra" vessels should be broken after coming into contact with the unclean animals/creatures.
In the other group of unclean animals/creatures there is no mention of them defiling anything other than the human beings who consume and touch them
Leviticus 11:29-34 KJV
29 These also shall be unclean unto you among the creeping things that creep upon the earth; the weasel, and the mouse, and the tortoise after his kind, 30 And the ferret, and the chameleon, and the lizard, and the snail, and the mole. 31 These are unclean to you among all that creep: whosoever doth touch them, when they be dead, shall be unclean until the even. 32 And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherein any work is done, it must be put into water, and it shall be unclean until the even; so it shall be cleansed. 33 And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean; and ye shall break it.
Do the other creatures mentioned in this chapter also defile other vessels?
