Is TS4 Cats & Dogs worth it?

I have the game and have played with it four times. I have never had an ep with this amount of bugs. Somethings work...sometimes. I had to sell a vet clinic because I wasn't able to do exams... or treat (this with the highest priced instruments) I have been waiting for this game since it was announced but I'm really disappointed this time. In keeping with the price and the tradition, I expected a more useable game. I hope they don't wait too long to patch it....
