Token seems to be legit.

Contract locking ether found:
Contract CryptoZoon (CryptoZoon.sol#8-118) has payable functions:
- CryptoZoon.receive() (CryptoZoon.sol#85)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

CryptoZoon._transfer(address,address,uint256) (CryptoZoon.sol#47-75) uses timestamp for comparisons
Dangerous comparisons:
- antiBotTime > block.timestamp && amount > antiBotAmount && bots[sender] (CryptoZoon.sol#53-55)
Avoid relying on block.timestamp.

- buyFeeRate = _buyFeeRate (ZoonERC20.sol#48)
ZoonERC20.setMinTokensBeforeSwap(uint256) (ZoonERC20.sol#51-57) should emit an event for:
- tokenForBosses = _tokenForBosses (ZoonERC20.sol#56)
CryptoZoon.antiBot(uint256) (CryptoZoon.sol#109-116) should emit an event for:
- antiBotAmount = amount (CryptoZoon.sol#113)
Emit an event for critical parameter changes.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (Uniswap.sol#148) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (Uniswap.sol#149)
Prevent variables from having similar names.
