I am not understanding, does the smart contract have 1 NFT or many NFTs.
Or is it that I deploy one smart contract for each type of my NFTs like dogs, cats... ? or it doesn't matter ?
And when I own a NFT, is it that I own a mapping in the contract token id => my eth wallet adress?
does the smart contract have 1 NFT or many NFTs
The ERC-721 standard defines a smart contract as a collection of multiple NFTs.

It depends on your use case. There's no "best" or "correct" way.

Technically, nobody owns the mapping. But in most cases, your address is the value for the token ID key in the mapping.
