Questions
Can guinea pigs eat cucumber every day?
Yes, as part of the daily fresh food. It’s best to rotate: several kinds of greens are better than a lot of one.
Can rabbits eat cucumber?
Yes, but only a little. The RSPCA lists cucumber with carrots and celery as treat vegetables. Non-leafy vegetables should make up a smaller proportion of the diet (RWAF).
