[Rise of Cats] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract ticker () contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Contract ticker () has length of 0 chars.
Not a direct threat, but may indicate unreliable intentions of developer.

ROCNFT.uint2str(uint256) (contracts/contracts/ROCNFT.sol#27-47) performs a multiplication on the result of a division:
-temp = (48 + uint8(_i - _i / 10 * 10)) (contracts/contracts/ROCNFT.sol#41)
Consider ordering multiplication before division.
