I was going to say My Cavy Angels, but I see someone already did.

I've always heard wonderful things about them as well. Did you run through a breed selector to see how they come up for you, based on your lifestyle and situation and all? You can google: dog breed selector
Iams and Animal Planet each have one.

You can also check with the breed club, they usually have a page on the web site along the lines of "is this breed right for you?"

Maybe search for a cavy forum and check things out there? I have had lots of help and info from the bichon forums I am on!

Good luck!
