its really left to your judgment but make sure that the food items are not to big. no one can have you explain the size of your animal and judge what you should or should not feed it, you have to look at it and decide for yourself. two smaller items may end up being to much and there is no reason to over feed your animal especially if you are feeding every week. you do not want your animal to regurge its food. that can cause all kinds of problems even death. what ever you decided just be careful.
