KittenPye Token

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

KittenPye.clearStuckBalance() (#884-886) sends eth to arbitrary user
Dangerous calls:
- address(feeaddress).transfer(address(this).balance) (#885)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)
