Can I give the same food (Nutrience) to my cat and dog?

No.

Cats and dogs have different dietary needs. Contrary to dogs (who are not only carnivores, and cannot survive on meat only), cats are entirely carnivores. And, also contrary to dogs, cats are incapable of producing "taurine" (amino acid) and they obtain this by eating meat. A lack of "taurine" can cause blindness and cardiovascular problems. Nutrience has been formulated to give the correct quantities of ''taurine'' in order to satisfy the needs of cats and dogs.
