FLOKITTEN.addLiquidity(uint256,uint256) (#1232-1245) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1237-1244)
Ensure that all the return values of the function calls are used.

FLOKITTEN._approve(address,address,uint256).owner (#1137) shadows:
- Ownable.owner() (#561-563) (function)
Rename the local variables that shadow another component.

- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#1023-1025)
Emit an event for critical parameter changes.

SafeMath.trySub(uint256,uint256) (#130-135) is never used and should be removed
Remove unused functions.
Additional information: link
FLOKITTEN._previousLiquidityFee (#840) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.
Additional information: link
solc-0.8.4 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.

Low level call in Address.functionDelegateCall(address,bytes,string) (#501-507):
- (success,returndata) = target.delegatecall(data) (#505)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
Additional information: link
Variable FLOKITTEN._maxTxAmount (#848) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#335)" inContext (#329-338)
Remove redundant statements if they congest code but offer no value.

Variable FLOKITTEN.reflectionFromToken(uint256,bool).rTransferAmount (#957) is too similar to FLOKITTEN._getTValues(uint256).tTransferAmount (#1051)
Prevent variables from having similar names.

FLOKITTEN.slitherConstructorVariables() (#810-1301) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000 * 10 ** 6 * 10 ** 9 (#849)
Use: Ether suffix, Time suffix, or The scientific notation
Additional information: link
FLOKITTEN.numTokensSellToAddToLiquidity (#849) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
isExcludedFromFee(address) should be declared external:
- FLOKITTEN.isExcludedFromFee(address) (#1133-1135)
Use the external attribute for functions never called from the contract.
