As was said, the hairs on the violin bow are made from the tail hair of horses, gotten when the horses are groomed.
In the old days, the violin strings were made of animal gut, usually sheep or cattle when this was left over from the usual slaughter of these animals for food. However, in modern times most strings are made from metal or plastic.
The Cat gut rumor originated as a joke, because a badly played violin sounds like a cat screeching.
Damn, you burst my bubble! But hmmm... You may have given me an idea. I can probably make this rumor into a legitimate science experiment.
