Man! That Rat is HOT!

Pet Rat Information Sheet - all you need for happy healthy pet rats: "In hot weather it is important to protect rats from heat exhaustion and dehydration. rats regulate their temperature mainly through the tail and foot-pads, so if you provide a bowl of cold water a hot rat can cool herself down by paddling in it. A fan placed near to the cage will provide a cooling breeze. You can also give your rats frozen vegetables (e.g. peas) as ice-lollies, and ice cubes can be added to their water-dish. Make sure that the cage is not in direct sunlight in hot weather."
