There seems to be a misunderstanding in the community where some simmers seem to think that The Sims 4 Cats & Dogs Expansion Pack will only bring, well, Cats and Dogs. Although this Expansion Pack’s name could’ve been better, we’re here to set the record straight and let you know that no, Cats & Dogs won’t be the only animals in The Sims 4 Cats & Dogs Expansion Pack.
Beside kittens, cats, puppies, small dogs and large dogs, there are also foxes! They don’t act like any other NPC animal – they can be created in Create A Pet and added to your household!
In CAP.

We still have to find out what specific gameplay will come with foxes, but we’re almost sure that they won’t act entirely like dogs.
In an interview with GamesRadar+, Grant Rodiek confirmed that there will also be racoons! However, we’re not sure if they’ll be anything different from raccoons in The Sims 3 Pets and if they bring unique gameplay.
SimGuruDrake confirmed that Raccoons are basically pets as well and that they can be created in Create A Pet!
you’ll be able to take your Cat/Dog/Fox/Racoon with you to other worlds (minus Sixam)
