It is usually just a passing thing in cats, like a croaky voice in a human. It should be okay, but take your cat to the vet to get it checked up to be sure.
I think you just need to get a mechanic to look at it or something. Or you may just need a new one. It depends how badly it was broken.
No idea. Good luck with your finding, but I really don't think you have much chance with this.
I love it too! I took it at school! My cousin is a history and Social Sciences teacher! I love to learn about the 1900's and lots of inventions and things! I also love the Laura Ingalls-Wild series! It is so amazing! Also is the best movie ever! The Native Americans are really cool too!
