summer provision is a tablespoon each of the chow and vegetable-fruit mix with one or two crickets. The winter diet is reduced by one-fourth and crickets are eliminated. The lesser mouse lemur (Microcebus murinus ) can be maintained on the same diet by adding a cricket to both the winter and summer diets. Obesity will result if winter diets are not reduced. Mirza coquereli, in contrast, does not enter torpor (a period of lethargy resembling hibernation), and no dietary change is required. It will consume about twice the amount in the summer as the lesser mouse lemur.
Indrids are obligatory folivores that have specialized in detoxifying various classes of leaf compounds, such as tannins. As a consequence, their captive diets require much more attention than that of other lemurs lest they quickly sicken and die. Sifakas pose particular problems in that they reject new items in their diet until they see and smell other conspecifics eating them. Leaf fiber (e.g., mango, sumac, mimosa, sweet gum, and tulip poplar) appears to be critically needed for their health. Deciduous leaves wrapped in plastic and frozen will be accepted after thawing. The seed pods and flowers of such plants as mimosa, redbud, and maple are also important food items, but they might cause diarrhea if introduced abruptly in large amounts. Browse is best presented by tying it to vertical supports. Peanuts and oak nuts should be limited because of their high fat content, but they are preferred foods, so they might help a sick (underweight) sifaka to recover from illness. Sifakas seem reluctant to drink water, and few will use a water bottle. Open bowls are more likely to be used, and browse can be sprayed with water.
Aye-ayes will reject monkey chow even if it is mixed with honey, coconut milk, milk, or fruit juice. They have been successfully maintained on commercially available foods, including a wide variety of fruits, cucumbers, coconuts, corn on the cob, sugarcane, raw eggs, and insect grubs, such as mealworms, waxworms, and various wood-boring larvae. Raw eggs should be limited to no more than three times a week because of the biotin-binding properties of avidin in the whites. Vitamins can be added to a gruel made of sweetened condensed milk, high-protein baby cereal, and eggs. Insect grubs appear to be the most-favored food items, as well as foodstuffs that are high in sugar or fat. Aye-ayes are not seen to drink often, but they will lick water from a bowl by using their specialized third digit (Napier and Napier 1985, pp. 93–94).
Lorises are adequately maintained on a diet of unsoftened, cracked monkey chow combined with chopped fruits and vegetables, crickets, and occasional mealworms. Separating feeding sites widely will reduce fighting over food. Yogurt and additional food should be provided to pregnant and lactating females. Lactation lasts for 6 months, but juveniles begin to eat solid food at 2–3 months.
Galagos—and in fact all lorisids—need hard elements in their diet to remove tartar or plaque from their tooth combs and canines. If they are not provided or if the teeth are not cleaned, these accumulations can cause severe gingivitis, tooth
