Question: **You are a intelligent adult quadruped; suddenly, you find yourself in a humanoid body due to magic! How long does it take you to learn how to move in your new body?**

Imagine a race of sapient quadruped mammals who have a society much like our own. They are able to function very well with their four-legged gait, but have almost no ability or concept of moving on two legs. Through magic or science, one of them suddenly transforms into a bipedal mammal.

What would be the process of the individual in adapting to a vastly different form such as this? How little or much might they struggle in learning to walk and properly balancing? Almost certainly, it would be easier for an adult to learn how to walk compared to a baby learning from scratch for the first time, as a matured adult will have better body control and intellect. 

**Is this something that might take a few minutes, a few hours, days, weeks, months, or more?** What factors might help the process go faster?

Answer: 
It will take some time and quite a struggle, as their entire brain has to be "rewired" to learn the new mechanism. 

You can compare it with how a human has to adapt when learning to move on a wheelchair or using crutches. On day 0 it will be a mess, after one or two weeks the movements will be as swift as in the original conditions, and with some more practice the subject can even play sports where coordination is even more important.

Of course the more frequent the practice, the quicker the adaptation.
I would hazard to assume that, regardless of the -grade, downgrading from 4 to 2 legs would just be a matter of 're-learning' how to balance as a new bipedal creature. As they would still have a fairly good grasp on how to use their legs, being on only 2 wouldn't be too much of a hassle; if we're dealing with a younger youth, the process of re-balancing might take 2-3 days to fully adjust, whereas adults could have a couple of (long) hours of reacclimation, and will be wobbly hobbling along in at least a day. HOWEVER, if they have a tail, and are well-versed in it's dexterousness, the process would be expedited to an extent.
