SakuraNeko.swapAndLiquify(uint256) (#1072-1096) performs a multiplication on the result of a division:
-half = contractTokenBalance.mul(liquidityShare).div(10000) (#1074)
-rest = contractTokenBalance.sub(half.mul(2)) (#1076)
Consider ordering multiplication before division.

SakuraNeko.addLiquidity(uint256,uint256) (#1134-1147) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1139-1146)
Ensure that all the return values of the function calls are used.

SakuraNeko._approve(address,address,uint256).owner (#1014) shadows:
- Ownable.owner() (#417-419) (function)
Rename the local variables that shadow another component.

SakuraNeko.setMaxTxPercent(uint256) (#918-922) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 4) (#919-921)
Emit an event for critical parameter changes.

SakuraNeko.setDeveloper(address)._developer (#762) lacks a zero-check on :
- developer = _developer (#763)
Check that the address is not zero.

Ownable.unlock() (#464-469) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#466)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#362-383) uses assembly
- INLINE ASM (#375-378)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#230-233) is never used and should be removed
Remove unused functions.

Additional information: link

SakuraNeko._previousLiquidityFee (#712) 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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#362-383):
- (success,returndata) = target.call{value: weiValue}(data) (#366)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable SakuraNeko._maxTxAmount (#724) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#242)" inContext (#236-245)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable SakuraNeko._transferBothExcluded(address,address,uint256).rTransferAmount (#892) is too similar to SakuraNeko._transferToExcluded(address,address,uint256).tTransferAmount (#1180)
Prevent variables from having similar names.

Additional information: link

SakuraNeko.slitherConstructorVariables() (#686-1203) uses literals with too many digits:
- _tTotal = 1000000 * 10 ** 6 * 10 ** 9 (#700)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

SakuraNeko._tTotal (#700) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- SakuraNeko.isExcludedFromFee(address) (#1010-1012)
Use the external attribute for functions never called from the contract.
