True practitioners do not sacrifice live animals if they can avoid it. If it is absolutely needed, they use chickens and goats, not cats. Get your facts straight people before you post answers for someone else. Unless you've studied or been a part of either religions practices, please don't speak like you know anything. It only spreads stereotypes and lies. If you want to know the truth, READ A BOOK> It's an amazing concept. Try the works of Migene Gonzalez-Whippler or Luisah Teish as a start.
No cats are not sacrificed. When it is needed which is not very often it is usually chickens, goats, farm animals. In my house we have only used birds. In Haiti pigs, cows, chickens, are sacrificed all the time. That is also because they have grocery stores to buy there meat from.
