Small animals are just that…small! You don’t want to overfeed them or they will get fat, which will tax their hearts.
Hamsters and gerbils should eat one tablespoon or less of food per day. For a treat, they can have unshelled nuts with no salt added. Do not give your hamster or gerbil iceberg lettuce, tomatoes, chocolate, raw beans, potatoes, or sugary or salty foods. Too much green food will cause diarrhea. Never give sticky food to a hamster, as it will stick to their pouches.
Guinea pigs love grass hay and green foods, in addition to high-quality pellets. They need vitamin C, such as kale, dandelion greens, collard greens and peppers. They should be fed twice a day. Great treats for your guinea pig include apples, apricots, bananas, berries, cherries, grapes, kiwi, melon, oranges, pears and strawberries.
Do not give them celery – they can’t digest the “strings.” Do not feed them raw beans or rhubarb, as those foods are poisonous to these animals.
Your bunny will love you for providing grass hay, and they can eat it without restraint. Pellets should be fed in the amount of no more than 1/8 cup per day. Avoid high-starch or fatty foods such as beans, breads, seeds, peas, corn, nuts, cereals, oats or other grains, but they can have kiwi, strawberries, pears, melons, apples, oranges and vegetables in limited quantities.
