Some more general info to add to MarianT's:
Foxes and raccoons can be made in CAP (Create a Pet) and can also be taken to a vet just like cats and dogs
There are various breeds coming with the pack but the team will go into more detail in the future (unspecified timeline) Scottish Fold has been confirmed but nothing else yet! lol
There is the same pull/push manipulation in CAP and there already is in CAS
No new Supernaturals in the pack - this isn't a big surprise though as we know this time around including supernaturals in packs isn't really going to happen.
