Squirrels are highly active, mobile animals. They communicate by chirping or chattering. The tail is also an important source of passing on messages. Flipping the tail, waving it back and forth, stretching it backwards or carrying it high above the back, each has its own meaning. It is important for a squirrel owner to understand that squirrels need a varied diet and that you cannot get away with a standard ready-made or “all-in-one” food. In addition, tropical squirrels need a lot of fruit in their diet which makes looking after them more expensive. Squirrels do not belong in a small cage so in order to own squirrels you need ample space, preferably an (outdoor) aviary or enclosure with sufficient area and height (tree squirrels). Know also that solitary squirrels cannot continuously be kept in pairs and that if you keep more than one animal you will also need several aviaries. Also provide the squirrels with fresh, clean branches on a regular basis. It is important to provide your squirrel with branches as they are important for gnawing, furthermore the saps under the bark are also good (necessary) for the squirrel.
