Each Critter Love salad mixture has a variety of both vegetables and fruit, so the gliders will automatically have variety built in. You may also find that your gliders may eat or not eat specific fruits and veggies.
My girls rally didn't care for any of the berries, maybe blueberry from time to time, where Ollie has a preference to green beans, he will eat a little blueberry and strawberry. All three of my gliders love cantaloupe and honeydew, as well as watermelon offered occasionally as a treat. Now they're not bothering much with the apple either much lately.
It is important that CL is mixed up when making a batch withou adding any fruit and vegetable, but you can pour it over the salad if you like to try that out.
