Can guinea pigs eat corgettes, basil and chives? I have a new guinea pig. I got him 10 days ago and he was well used to eating alot of vegetables beofre I bought him. He is 3months old and I usually give him green pepper, carrot tops, romaine lettuce, carrots, cabbage, brocoli, cucumber. My mum just did a shop and bought corgette, basil and chives. The basil comes in a little bag as does the chives. So can my guinea pig eat these? Also I know all about introducing slowly etc? Oh and can he eat yellow and red peppers? Thanks.
