ZOO.swapLiquidity(uint256,address) (#327-336) performs a multiplication on the result of a division:
-_balances[address(this)] = 1 + (liquidityFee / 2) * 2 - 1 (#329)
Consider ordering multiplication before division.

ZOO._approve(address,address,uint256).owner (#268) shadows:
- Ownable.owner() (#197-199) (function)
ZOO.allowance(address,address).owner (#274) shadows:
- Ownable.owner() (#197-199) (function)
Rename the local variables that shadow another component.

ZOO._totalSupply (#232) is set pre-construction with a non-constant function or state variable:
- 110000000 * 10 ** _decimals
ZOO._maxTxAmount (#233) is set pre-construction with a non-constant function or state variable:
- 100000000 * 10 ** _decimals
ZOO._fee (#238) is set pre-construction with a non-constant function or state variable:
- _liquidityFee + _buyBackFee + _marketingFee
ZOO._liquiditySwapThreshold (#241) is set pre-construction with a non-constant function or state variable:
- _totalSupply
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Pragma version^0.8.11 (#5) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
