Handling : The desire for survival is same whether in animals or human beings. You may be aware of the ability of even tiny animals to scratch and bite. So we won't say any more on the matter apart from reminding you of the severity with which even the smallest cuts and scratches should be treated in the biology lab. You should always take normal hygiene precautions when handling animals and their cages, litter or bedding. Cages should be regularly sterilized and bedding changed. Wearing rubber gloves and washing hands afterwards, are the exercises you should not forget. You must also keep up-to-date with your anti-tetanus injections. It is important that you should consult your doctor about the time interval between two consecutive injections.
