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.

Reentrancy in CryptoZoon.constructor(string,string) (CryptoZoon.sol#22-35):
External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (CryptoZoon.sol#30-31)
State variables written after the call(s):
- _approve(address(this),address(uniswapV2Router),~ uint256(0)) (CryptoZoon.sol#34)
- _allowances[owner][spender] = amount (ERC20.sol#276)
- uniswapV2Router = _uniswapV2Router (CryptoZoon.sol#33)
Apply the check-effects-interactions pattern.

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.
