Hi everyone!

I'm new on these forums, but I had a couple questions to ask right off the bat...
I know that by going to the Rabbit Forums I'm going into a bit of a biased area, but I wanted to ask a couple questions comparing rabbits with guinea pigs.
Do rabbits or guinea pigs generally smell more?
Are rabbits or guinea pigs usually more calm and friendly?
I heard that rabbits will often follow their owners around the house-is this true?
Thanks a lot to anyone who replies-I will probably have plenty more questions, but thanks for answering these ones!
