TelegramCat.swapBack() (#414-434) performs a multiplication on the result of a division:
-liquidityTokens = contractBalance * (buyFee.liquidity + sellFee.liquidity) / (buyFee.marketing + buyFee.liquidity + buyFee.bb + sellFee.marketing + sellFee.liquidity + sellFee.bb) (#416)
-ethForLiquidity = ethBalance.mul(liquidityTokens).div(totalTokensToSwap) (#428)
TelegramCat.swapBack() (#414-434) performs a multiplication on the result of a division:
-bbTokens = contractBalance * (buyFee.bb + sellFee.bb) / (buyFee.marketing + buyFee.liquidity + buyFee.bb + sellFee.marketing + sellFee.liquidity + sellFee.bb) (#418)
-ethForbb = ethBalance.mul(bbTokens).div(totalTokensToSwap) (#429)
Consider ordering multiplication before division.

TelegramCat._transfer(address,address,uint256) (#342-411) uses timestamp for comparisons
Dangerous comparisons:
- launched && block.timestamp > launchEpoch + 10 && ! phaseOne (#365)
- launched && block.timestamp > launchEpoch + 60 && ! phaseTwo (#372)
- launched && block.timestamp > launchEpoch + 600 && ! phaseThree (#378)
Avoid relying on block.timestamp.

Pragma version^0.8.16 (#31) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.16 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.
