I'm a bit late to the party. I didn't get Cats & Dogs until yesterday. In fact, my simming came to a halt for several months due to life cropping up. But finally caught up on the stuff packs I missed and of course, Cats & Dogs. To echo many, I LOVE the world. Brindleton Bay is my favorite part, hands down. Hehehe, love the cheap starter house that sits on the beach. I could go on and on about how pretty the world is, but I won't XD.
CAP is pretty cool. I've enjoyed it quite a lot so far. Created my actual kitty plus a dog I had growing up. It's fairly intuitive, though was a little disappointed that you can't save your breed template. Probably shouldn't have been (by template, I mean, saving the dog or cat you created as an actual breed in CAP that you can use later). I eventually figured out how to save things to the gallery so wasn't too bad, just one of those things in my wishlist that would be cool, one less step type of thing.
Game play is where I'm not as- fond of it, sadly. While I understand not being able to control the pets, I would at least be able to look at their stats. Ages, family tree, etc. Simple things. So that I'm a bit meh on, though I'm ok on not being able to control them. I played for several hours, created a sim and her dog. I created another sim and his dog and moved them into Brindleton Bay. Eventually, there was some romance between the Sims and they combined households. Now, this is where I'm very annoyed and it's actually putting me off playing again until they fix it. The dogs are opposite genders. Both Sims are good friends or better with both dogs. I have used the "Be nice to" command multiple times as well as the "Encourage to mate with". And it has never happened. They seem to get along well enough otherwise, but I have probably encouraged to mate over 50 times with no success. While looking up this problem, I found others have had similar issues, as well as issues when a successful breeding has occurred.
My plan was, to eventually see how a breeding business or pet-type business would work. Which is another reason I wish I could see at least the ages and family tree of the pets. But at the moment, my game has come to a grinding halt. Over all, I do like the pack, just- very frustrated at this kind of game-breaking bug.
