This information provides general advice for customers with pets and livestock which may be useful when preparing for a power cut. For specific information, or details about more unusual animals, we recommend that you contact your local pet shop or supplier.
Tropical Fish
Most tropical fish will not experience any stress if the power cut is only for a short length of time, typically two to three hours. Remember that the mains-operated air pumps, filters and heaters used in many fish tanks won't work while the electricity is off.
-
Without a heater, the water temperature in the tank will fall, especially in cold weather. Placing sealed drinks bottles of warm water inside the tank can help maintain an acceptable temperature - about 78F for many tropical fish.
-
An inexpensive, battery powered air pump also helps to keep the tank water healthy for your fish while the electricity is off.
-
For longer power cuts, you may need to do a partial water change to compensate for the absence of proper water filtering. Ask your local pet shop for more information about this.
Pigs & Poultry
Ventilation, heat, light and food are the main things to consider when caring for livestock if your electricity supply is interrupted.
-
Ideally, electrically-operated fans should switch to generator power if there is a power cut. If you do not have a generator available, use automatic drop-out flaps in the building to provide natural ventilation. You can also increase air circulation by fully opening ventilation flaps and doors.
-
Young animals are particularly vulnerable in cold weather so provide extra insulation and straw for bedding. Consider moving animals you feel are especially at risk to temporary accommodation with bottled gas heating.
-
To lay productively, most hens need a good source of light. Consider obtaining a generator to provide enough lighting for feeding, inspection and service.
-
If you usually use automatic feeding, make a contingency plan for manual feeding. Try to keep enough food stock for your animals in reserve, especially in winter, so you'll still be able to feed them if your electricity is interrupted.
-
Mains electric fencing won't work in a power cut. If you feel this might be a problem, consider buying a battery powered unit to provide an alternative source of electricity.
