Do you think than Cats and Dogs will be the only pack to include pets?

I would love it if animals was something we could expect in every pack like we kinda do with new deaths, lifestates, woohoo spots, etc. I'd be fine if they weren't super advanced. But it would be cool if they added llamas to the adventure pack (if it's set in south America), then maybe some farm animals in a farm pack, rabbits in a magic pack etc etc.
