Penguin sweaters, also known as penguin jumpers, are sweaters which are knitted for penguins that have been caught in oil slicks. When an oil spill affects penguins, they are dressed in knitted sweaters to stop them preening their feathers and to keep them warm, since the spilled oil destroys their natural oils. This also prevents them from poisoning themselves by ingesting the oil. The sweaters are removed and discarded as soon as the penguins can be washed.
Harp Seal pups only stay white for the first ten days of their life. These poor animals are being killed annually in a hunt sponsored by the Canada Government. Luckily, there are some wonderful organizations such as the IFAW who are doing their best to stop this cruel and unnecessary sport.
