Article in English: Squirrels need room to run a bit. Make sure the cage is at least 2'2'x3' with shelves, a bed, and places to hide and climb.  Keep a ceramic water source in the cage. If it's plastic the squirrel will chew, destroy, and possibly eat it. Provide it with toys to play with. Good ideas are pinecones, clean sticks, or a clean, thick dog bone. Bad ideas are anything it can rip apart, choke on, and throw the stuffing all over the place (like a bean-stuffed toy).  Include objects to grind his teeth on, as they never stop growing. They need social interaction, especially if your baby is a loner. This should include at least one hour of outside-the-cage fun time every day. If you don't have a room safe for this, either get a larger outdoor cage for them to spend time in (you'll eventually need one anyway, but don't transfer the baby to the outdoor cage without a travel carrier) or move it to a different cage in a different part of your house.  Do not allow the baby to play outside while not contained. Hawks and other predators are much faster than you and may snatch up the baby before you have a chance to react.  The baby may also get spooked and run away, unable to return.    It is a good idea to let them get used to heights and curtain rods will be a great help here. You don't want your baby to be crawling on the ground once it gets outside and many hand-raised squirrels tend to do just that, ending up easy prey for snakes, cats etc. Rehabilitators will pair a baby squirrel with a friend before either opens their eyes so they bond together. This is yet another reason to take the baby to a rehabilitator: two squirrels will help each other survive in the wild in a variety of ways.  A baby squirrel kept in a small cage too long can have growth deformities from the cramped spaces or from circling the small cage. Once the baby stops taking formula completely, stop taking the baby out.  He will need to learn a natural fear of humans to ensure his safety in the wild. At four to five months of age the squirrel will need to be...
