PLEASE GUYS:...DON'T GIVE UP!! I ALMOST DID TOO!
Here's the key...
#1. YOU GOTTA PLAY IN FULLSCREEN.
#2. Once enough pets get on the screen, the game will slow down and they'll get easier to handle. This happens around the 1800 point mark. With a little practice, you'll get better...once you can hit 1800 it'll be downhill from there. You may die your first few attempts after getting 1800 points, but it is soooo easy to make it after that.
#3. Once you learn which cries mean what, ("gruslen needs potty" for example) you'll get much faster to boot.
After about 2000 points, the game slows done considerably. If you have a spare attempt (life) or two you'll probably make it. Once you get to 3000 points it's a snooze-a-palooza. It takes forever at that point for anything to happen. You basically sit around watching all these petpets all bunched together walking all choppy and sit and eat a sandwich waiting for one to finally whine. You'll even have time to mop and rack up 5 points per mopping job by then! Eventually you'll never die...you just play as long as your patience will allow.
Please, please hang in there. I couldn't beat 800 points my first day of trying for the avatar. Then yesterday...I made it to the avatar. By the afternoon I was able to manage playing a single game for 5 hours straight until I finally gave up and went to the potty.

That game really needs a pause button....LOL.
So, from not being able to break 800 points; to this in one day:
....if i can do it guys, I KNOW you all can! Don't give up, and trust me...it will get easier. MUCH easier.
