In The Sims 4 Cats & Dogs you can have up to 7 Cats / Dogs in 1 household as the household limit is 8 Sims / Pets with 1 Sim needing to be in a household in order to take care of pets. However, this limit can be adjusted with a reliable mod – MC Command Center.
Right now the MC Command Center is the only mod out there which allows you to extend the number of Sims in a households. All other mods have been affected by the latest game update and it could take some time for them to be updated.
You can get MC Command Center’s latest mod version HERE! Select the right download link that says McCmdCenter_AllModules. Extract the .zip file to Electronic Arts > The Sims 4 > Mods. When it comes to extending the household number you’ll only need these 2 files:
Make sure you have Mods / CC enabled in your game options, as well as script mods!
After installing these mods you are now ready to extend the Household number. Select any computer in The Sims 4 and select “Mc Command Center”. Go to MCCC Settings > Gameplay Settings > Maximum Household size and select the maximum amount of Sims / Pets allowed in households (max number is 25).
After you select “OK” you will have to restart the game in order for it to take effect.
With this mod you are able to adopt cats and dogs without having to worry too much about the limit. You can also use testingcheats true > shift + click on a Sim / Pet to “Add to Family”. However, please note that you cannot add more than 8 Sims to the household using Create A Sim – you’ll have to use the tools that are given to you for adding Sims in live mode.
lease note that this feature is not recommended for those with low-spec computers.
