Hi again,I knew I had something else to Ask! I've been doing my reading to learn as much as possible about how to properly care for my new fur-babies.All sites say fruit & veggies daily, but the ASPCA site says no corn. Now, I have two different kinds of rat food & both have corn in them!! Is this true - no corn?? What foods do you recommend - bare in mind I'm in a very small town in rural Ontario, Canada. It's 1 1/2 hrs to the closest Petsmart, so I'll likely be buying online!Also, I have the "All Living Things Rat Starter Home" (28" L x 17.5" W x 30" H), it has water bottle, 2 hide-away homes, 3 levels, excersaucer, hammock & 2 feeding stations. Is this big enough for my 2 boys? If in the future we get another boy would I need to upgrade or do you think it's big enough for 3?Thanks!
