I'm sure not a lot of people would agree, but I'd rather just pay a higher price upfront for an EP that's sold as a complete bundle (I can understand because of inflation and rising development costs), rather than chopping it up and pretending that the SP expands on an already-full EP.
As much as I love Cats and Dogs, it's missing a few touches. And I don't think the solution is to charge people for more pet clothes, and possibly pet beds and doghouses, whose lack players did complain about. Dogs can't even sleep on beds in this game, which I'm very keen on because ours loves to sleep on the bed with the humans. And kids can't walk their dogs without a mod, among other things.
The SP doesn't even have other animals, just rodents. I might understand if it had a fuller range of small pets like birds and reptiles, but the SP in itself seems bare too.
