A black cat crossing the road means bad luck in almost all countries except in the British Isles. Here, the black cat means good luck! The reason for why people often dislike the black cat is that it has been considered the witch's helper, and a friend of everything evil. If, however, a tabby or grey cat comes into your house and wants to stay there, that is a sign that you will get some money. 

Dogs can also predict the weather - if you see a dog eating grass, rolling on the floor or scratching itself excessively you can be sure it is going to rain. If a dog is howling at a door that is an omen of death, and if a dog whines when a baby is born, that baby will lead an evil life.  

Superstition says it's lucky to meet a herd of cows on the road and when cows lay on high ground that is a sign of good weather to come. But if cows lay close together or if they are laying very low, that means the weather will get worse.              

White horses have always beem considered lucky to see or own. A horse with white 'stockings' is considered lucky, especially if the horse also has a 'star' on its forehead. As  weather omen, if horses stand in a group with their backs to a hedge a storm is on its way. 

Rabbits are considered lucky, and a rabbit's foot is a very well known good-luck charm. If you want a good month, then on the first day of the month you should say "white rabbits, white rabbits, white rabbits" when you wake up. This will ensure you have a lucky month. During Easter the Easter Bunny often comes to give out chocolate and small Easter eggs. 

Bats are animals which humans often are afraid of. It is considered bad luck to kill a bat, and it is a death omen if one flies into a house. If one flies past you - beware! That means someone is trying to let you down. Some people consider it lucky to keep a bone from a bat in your pocket, but that belief is not so common any longer.  
  
Spiders are an important ingredient in many old cures for illnesses, and should you happen to kill one, you may expect bad luck, as this old saying says: 
                            If you wish to live a thrive 
                            Let the spider run alive 
The reason for the belief may be quite simple: In the middel ages when flies carried around all kinds of spiders, it was important to have spiders, since they killed the flies. It is a good omen to see a spider spinning a web - then you will shortly get some new clothes. If a web drops on your face or clothes - particularly web from the little red spider, then you will soon get some money. Webs are also said to stop bleeding when laid over a wound. 

Ladybirds are considered lucky if one comes and sits on your hand. If you count the numbers of spots on its back you will see how many lucky months you have to come. To make the ladybird fly away (so that you can make your wish!) - you have to say: 
                              Ladybird, ladybird fly away home  
                              your house is on fire and your children are gone! 
Tradition says that the ladybird will take off because it understands our language. The truth is that it doesn't like our sweaty hands!
