Final answer:
True, Renfield consumes creatures to absorb their life force in Bram Stoker's novel 'Dracula'.
Step-by-step explanation:
The statement that Renfield eats his various pets because he wants to obtain their life force is True. In Bram Stoker's novel Dracula, the character of R.M. Renfield, a patient in an insane asylum, exhibits a peculiar obsession with consuming creatures such as flies, spiders, and birds in a delusional belief that he will absorb their life force or vitality, a concept he refers to as 'zoophagy'. This belief is deeply entrenched in his madness and is linked to the influence of Dracula himself.
