Not seeing a way to check the non-standard NFT of the MoonCats from the mooncatrescue.com project.
The early ones here seem to have been minted in Aug 2017, before the NFT token standard ERC-721 was in place.
Here is the MoonCat smart contract address: 0x60cd862c9c687a9de49aecdc3a99b74a4fc54ab6
Here is a short video on the "rediscovery" of these old (possibly second-oldest group) of NFTs.
