Cat trivia

Mum (Dr Jo) was talking cats all Easter weekend at the Sydney Royal Purina cat show. She asked people lots of questions (and not many knew the answers!). Can you do better? Here's some trivia questions about cats for you to guess (oops, answer knowledgably!):

1. How many teeth do cats have?
2. How many whiskers are on either side of the cat's nose and mouth?
3. Are more cats left pawed, right pawed or ambidextrous?
4. Are the feline front or back claws sharper?
5. Sir Issac Newton invented something useful for cats. What was it?
