Is TS4 Cats & Dogs worth it?

Well, value is in the eye of the beholder. I'd say it's worth the 40 USD. Others would say it's good but worth a smaller amount.

If you can wait, you should wait for a discount in the coming weeks just to save up. I was excited so I preordered. :D

Since animals bring a whole new dimension to TS4, I'd say yes.

Yep. I cannot wait to become a vet.

I think it's worth it. Sure there are a few bugs and glitchy things but for the most part I am very satisfied and think it was worth the purchase price. I pre-ordered and paid €40. It was an early birthday gift to myself. My birthday isn't for another 10 days but I couldn't wait that long to play, ha.

It looks a bit buggy for me to buy right this moment.

But I'm totally gonna get it.

I think on sale it is. EPs go on sale pretty common of all the packs, so if you find a sale on one, use it. That way you'll have some money left for your next Sims purchase like two SPs or one GP.

Lots of lacking features, can not even Kitty train kittens

Yes - they did an amazing job on this pack. I really like it a lot.

I got Cats & Dogs cheaper using a voucher and I'm glad that I was able to do that. I think for the price there should have been a lot more content included.

There are only 2 bed types: small (round) and large (square). In previous versions there were mattress type beds, basket styles and outdoor kennels/houses.
Also, there are only 3 or 4 toys (2 balls and 2 squeakers). What happened to tug toys, teddies and novelty hot dogs? I do like the toy baskets but my dog hardly uses it!

I am looking forward to setting up a vet clinic and create-a-pet was much better than I had anticipated.
