Guinea Pig

What foods are bad for guinea pigs?


Before starting with the foods which are totally forbidden for guinea pigs, you should pay attention to some that should not be given to these rodents very often:

  • Grapes

  • Oats

  • Barley

  • Pips

  • Seeds

  • Bread

  • Parsley


Forbidden foods for guinea pigs:

  • Meat

  • Animal derivates

  • Sweets

  • Mushrooms

  • Chocolate

  • Coffee

  • Madonna Lily

  • Salt

  • Potatoes

  • Avocado

  • Sweet potatoes

  • Ivy

  • Rhododendron

  • Onion

  • Preserves

  • Sugar

  • Mint


Why shouldn't you give these foods to your guinea pig?


Products of animal origin such as meat, eggs or milk come very ill-advisedly, because the guinea pig is a herbivore, meaning it only eats products of a vegetable origin. Under no circumstances should you give it this kind of food, since it's completely outside its natural diet.


Even though they originate from vegetables, there are certain species of spices and plants which aren't appropriate because they can be poisonous if consumed in large quantities. Ivy, for example, is also poisonous for dogs and cats.


Finally, we must add that products containing sugar are completely inadvisable for guinea pigs, since they should not consume this type of food. Its consequences include blindness and intestinal problems, among other things.

Best fruits for guinea pigs:


Fruits are a fantastic dietary supplement thanks to their high vitamin content. It's important to point out that vitamin C needs to be incorporated into the diet of your guinea pig. You should provide your pet with small portions of clean, fresh fruit three to four times a week. Remember to remove seeds or stones of some fruits, such as cherries.

  • Kiwi

  • Pineapple

  • Cherry

  • Strawberries

  • Watermelon

  • Papaya

  • Apricots

  • Banana

  • Apple

  • Blueberries

  • Mango

  • Tangerines

  • Peach

  • Loquat

  • Pear

  • Plum

  • Oranges

  • Nectarine

  • Melon


Useful information about fruits for guinea pigs:


Kiwis contain laxative properties, which are ideal if your guinea pig suffers from constipation. You must also know that it's a fairly acidic fruit, so you shouldn't give it to it too regularly. Apples are another good option for constipation and diarrhea, since they are great at regulating intestinal flora.


Tangerines and oranges are also fairly acidic, but they are high in vitamin C which is very good for your guinea pig. Melon and watermelon, meanwhile, are perfect for properly hydrating older guinea pigs as a result of their high water content. Pineapple helps to improve the digestive system of guinea pigs that are suffering from excess gas.


Finally, we add that bananas are a very good option owing to their high levels of potassium, sugar and hydrates. However, this fruit should be given occasionally and never in excess.

Best vegetables for guinea pigs


Vegetables are another source of vitamins and, in general, you can give them to your pet more regularly than fruits. Three to five servings a week will ensure your guinea pig is happy and well fed. We recommend:

  • Lettuce

  • Endive

  • Rocket

  • Courgette

  • Cauliflower

  • Cucumber

  • Corn salad

  • Aubergine

  • Spinach

  • Red pepper

  • Green pepper

  • Brussel sprouts

  • Green cabbage

  • Tomato

  • Alfalfa sprouts

  • Chicories

  • Celery

  • Carrots

  • Pumpkin

  • Broccoli (leaves and stalk)

  • Artichoke

  • Chard

  • Green beans


Useful information about some vegetables:


Carrots are ideal for preventing constipation and diarrhea, although you shouldn't give it excessively. It's best to offer it two to three times a week.


Peppers, rocket and corn salad are all vegetables which are high in vitamin C. Meanwhile, celery and artichoke (besides their moisturizing capacity) work as diuretics.


We point out the chard for ill guinea pigs, which works wonders for improving kidney issues or urinary tract problems. The artichoke, meanwhile, is good for the guinea pig's liver.


Overweight guinea pigs can increase consumption of aubergine, courgette and cucumber. On the other hand, guinea pigs who need to put on weight can make the most of vegetables such as chicories or pumpkin.
