Various questions

Question
Hi.
I have 2 pet rats, 1 grey husky rat and 1 pink-eyed dumbo rat. They have 24 hour food and water and have 2 sputniks to sleep in. I was wondering about a few things:
1) I read somewhere that a rats favorite food is any cereal product, is this true?
2) Do rats like bathing? I tried it once with them but they didn't seem to enjoy it or is it just different between rats?
3) My rats have orange teeth, is this healthy?
4) Finally, can rat nails get too long? Again i read somewhere that they can in-grow into there skin so is there anything i can do to prevent this or will they do it themselves?
               Thanks.

Answer
You need to see my site, sandyscrittercity.com.  Check out the page on rat teeth and also on proper diet for the answers you need (and yes, orange teeth are normal and NO, not all cereal is ok for rats to eat)  Also the nails do not usually grow out of control to the point they can grow into the skin. Thats just someone talking trash that know nothing about rats, obviously.
