Yup
Heres how:
Step one. Go to the neighborhood (yes you MUST be at neighborhood in order for this to work)
Step two. Press Ctrl + Shift + C at the same time
Step Three. A white box should appear, If not Try again. In that white box type in "Boolprop testingcheatsenabled on" (not in quotations)
Step four. Go back to the family and go to the Skills bar & just drag them up
You can also do this with your needs, Personality and many more
"boolprop testingcheatsenabled on" Can do much more than that

Unfortunately there is no Sims 3 cheat that maximises all skills...yet.
Just use the boolprop cheat in the neighborhood and go to your skills and just click and drag on them.
No sorry there is no motive cheat on the sims pets. Edit: There is none for Sims Pets, but there is one for Sims 2 Pets. It is 'maxMotives', also type in 'help' in the Sims 2. That will give you a large list of cheats. Note: Must be in Sims 2, or it will not work.
Try putting in the money cheat or fill all motives
on sims 2 pets you dont have any upstairs or any stairs at all
