I've had Pets since this morning.
Mind you I've only been playing for a few hours but I'm not as impressed as I thought I would be thus far.
First of all the first thing I did was hit the new town. It was alright. It didn't thrill me as much as I had anticipated. I explored a bit, looking around. I then went and adopted a horse. As soon as I did, my memories of the Sims 2 issues started to come back. I told him to brush the horse and so on and after a moment of standing around the horse moved towards him and somehow managed to wedge himself into a small gap in the barn he had been in at the time. Then it started. The no path complaint. The horse would move a step, he would move, the horse, him until finally I just crossed out the animation and tried something else.
When he finally got on the horse I chuckled to myself because I had been waiting for this, but it was a bit anti-climactic. He rode a few steps (the horse walked because he hadn't built his riding skill up enough to trot, etc.) He went to the end of the road and stopped. Turned around and walked back a few steps. Finally after a few minutes of watching this play out I had him get off the horse and go to pet it. He moved a step. The horse adjusted himself. Another. Another.
I gave up and clicked to mount and go home. (By the way I should put in when you go to mount you can saddle and if the saddle is not on the horse will spin like the sims do before the change clothing to put on it's saddle). I should also add that this can take a while. I sat there for quite a while before the horse did his magical spin and put it on. Then he mounted and started the long walk home. Like I said, the sim's riding skill was low so it was a slow pace.
Halfway there - because he lived all the way across town - I got annoyed and dismounted calling a taxi.
I decided to try a new family then. Husband and wife - Animal lover trait. (You can not pick cat, dog or horse lover trait if you have animal lover trait becuase it includes them all.) I made him a want to be a Jockey - a cool career choice - and created his wife and the horse. After moving them into a house I had him work on his riding skill. Of course, since you can control the animal now I saw the horses needs as well. It's basically just like having another sim in your household if you choose to control it. Like every other sims in the game you can leave them to their own devices and they will eventually take care of themselves, but many sims in this game don't appear to be too bright on that front, so I have little faith in the animals.
So, he was out riding and his wife adopted a cat via the phone - or paper. At the time there was only 2 choices, an elder cat or an aggresive kitten. She took the kitten. It arrived shortly thereafter like an adopted child. She awwwwwwwed and held it in her hands like a little football, sitting on the couch and watching TV. Meanwhile the husband reached his next level in riding and could trot. So he is riding around the town and she decided to hit the sack. As soon as the kitten was on her own the furniture started to take a hard hit even though I had bought the scratching post (Considering I have 7 cats IRL, I should have seen this coming). Not wanting to bother to have my sim get up and scold it since she was sleeping I allowed the cat to desimate the couch. It then promptly ran into a a bag my sim had bought for it and stayed there until her husband came home where it scratched him in greeting when he went to investigate the new addition to the family.
Before this, however, he came home and I told him to lead the horse into the makeshift corral I had made for it. A ton of path problems later the horse was napping and my sim who was saddle sore as well as I was only too happy to be done with it.
Since everyone was sleeping - except the slightly brain damaged kitten, I promptly got rid of the family and made another. This time he was just going to be a chef. I would do the Jockey thing later.
So, a short while later, his wife is sitting on the couch and a deer pops up outside her house. YEAH! Excited, I clicked on "Watch deer." She ran outside the house, back in, back outside, around the corner and onto the next lot to do this. After that I clicked on "Pet Deer." Of course, the deer wanted nothing to do with that but that didn't stop it from walking a few feet away, turning, walking away, turning, turning, and turning once more before it stopped and she walked up to it. Face to face it turned again and continued to do so, apparently trying to find a path to run. I sighed and made her go to bed while the deer eventually disappeared into the brush.
I've only been playing for a short time, but am a little less excited then I had been this morning. I've also noticed several lag issues cropping up. It has got smoother with time, but the freezing came back again like it did when I had the Late Night expansion in. I'm in no way giving up because I've waited too long for this.
I'll just wait and see what happens in the future.
