If you have a book on kitten care that you aren't using, offer to lend it. I like Laura's idea of making the information interesting.

"There is some really neat stuff in this book! I had no idea that etc etc etc." Just one or two things. Show them a cute picture or two in the book. THEN your friend should want to borrow it for sure!

Good luck! You have knowledge to share - make it fun!
