Your hamster may also show signs of inactivity. Wet-Tail develops in a hamster that is under a lot of stress. This condition, if not treated can be fatal. If your hamster exhibits these signs, take him immediately to your veterinarian. Because a hamster with wet-tail has extreme diarrhea, your hamster can become quickly dehydrated.
Treatment usually involves rehydration and antibiotics.
If your rabbit is biting, charging, and mounting your fee, this is generally caused by hormones. The treatment for this and other aggressive sexual behavior is spaying and neutering. Rabbits who bite also respond to dominance discipline. Rabbits are timid and should never be yelled at or hit. When your rabbit trys to bite, reach behind his head and press it gently but firmly to the floor.
