And thats about it, what do you think?

I love the pet contest idea. I had so much fun with such a thing in the original The Sims Unleashed.

I was surprised they added such a feature to The Sims Pet Stories, but not in The Sims 2 Pets. Hopefully they will give it to y'all this time around.

Sounds like a lot of fun! It is rumored that we may get a neighborhood, I totally love the Unicorn idea!

We almost have to get a neighborhood for this one. But I also hope that other neighborhoods can get NPC animals and such. Maybe like an Animal setup wizard for each neighborhood (so you wouldn't get squirells and deer in the middle of bridgeport), kinda like the weather setup wizard in Sims 2.

But I really like your ideas! I just don't think we're gonna get cows and chickens and such, unfourtunately. Too much for EA to code.
