  • Fresh Food Do you ever give your piggies wild foods?

  • No ๐Ÿ™ Milk is not safe. I would avoid probably all Vitakraft products.

  • Marlana Phillips Campbell

    OK thank you!!

  • Marlana Phillips Campbell

    What treats can I give my guinea pigs to teach them tricks?

  • Tim Harb

    I also use the folded c&c grid now. Just if you do fold one make sure it is on the side where there is no seam. I had to learn the hard way after breaking a few.

  • Allyson

    I give my gunnia pig ice burg lettuce and tomatoes and she has lived for 5 years

  • Tamara DiGiovanni

    Awesome information! My question is, are a few plain Cheerios okay to give as a treat? I don’t like pet store treats. I feed plenty of fresh organic foods. I eat Cheerios all the time and you know how bad piggies beg and make you feel for having the audacity to eat in front of them without sharing!

  • Tamara DiGiovanni

    Oh gosh, please ignore my picture! I was on a political topic before I came here!

  • Hi, Tamara! Cheerios, along with any other grain products (cereals, pastas, etc.), are not at all safe for guinea pigs. Don’t feel bad keeping them for yourself!

  • Samantha Clear

    I have ecotrition Guinea pig food and it has small seeds is it safe and healthy?

  • Terry

    To the designer of the Dangerous Foods List…This is the correct spelling of poisonous. Just trying to help ๐Ÿ™‚

  • phoebe wake

    Iceberg lettuce is safe but it just has no nutritional value, which is why it is said to be bad for them, because they are getting nothing out of it ๐Ÿ™‚

  • Lily Hirst

    I’ve given my guinea pigs some of these things are they are perfect when u look at these things just remember they can eat some of them just not on a regular baseis ie, lettece , sweet peas , seeds. Also k noticed there was no avacardo that’s poison for them!

  • Donovan Eady

    Iceberg lettuce isn’t poisonous, for guineas I used to think so, but then one time a pet sitter fed Porkers my eldest guinea pig a stalk, and it wasn’t on the list, but he’s fine, I just fired the sitter and had a little “chat” with him, but Porky’s fine, and Iceberg lettuce doesn’t have any nutritional value for guineas, so it’s kind of like if your really hungry and you eat a bag of Doritos, your hunger may subside, but your not really getting anything out of it. So in general, don’t feed your pigs Iceberg lettuce because your basically just filling them up.

  • Donovan Eady

    Peppers should be avoided, as well as any kind of grain, like seeds, rice, toast doesn’t pose as a fatal threat, but can give your piggies diarrhea and could make them sick, but they will recover, so avoid wheat and grains, if your food has grain in it, don’t worry, but I’m talking about rice and seeds, try to avoid iceberg lettuce because it has no nutritional value and you will be filling your piggie up. Hope this helps a few people!

  • tabby

    i feed my guinea pigs green beans,carrots,brocolli,dandelion leaves and hay.

  • Haley Mason

    What if your guinea had potato can it kill them? it was a white potato and both of them ate it, but unfourtenly one of mine passed and I don’t know the cause. ๐Ÿ™

  • Nicole

    Are the leaves of the Common Nettle ( Urtica Dioica) safe for guinea pig consumption? ( not all plants of this species have bristles that sting)

  • Justine

    I have been seeing a lot of posts about giving guinea pigs iceburg lettuce. DON’T DO IT. Not only is there no nutritional value, it causing bloating, gas, and discomfort. There is no point in giving them iceburg lettuce. Dark greens… Spinach kale and various other types of lettuce that are dark in color. Avoid giving them the stalk as well.

  • StarlaSkyy

    Bitch im not immature because i wanted to know an answer to a question, if i was fucking immature i would have just started feeding them cheese squares. The fuck? Use your damn head. I hope someone punches the hell out of you for being such an ass. I know if i could I would throat punch your stupid ass. But thanks for the information, dipshit.

  • Danielle Radtke

    Hi, I recently got a Guinea pig and he came with Vitacraft complete nutrition and it says that it has ground corn and flaked corn. Is that ok for him to eat?

  • While I’m not familiar with Vitacraft, we wouldn’t feed anything with any type of corn. We find that KMS Hayloft pellets are very good and not very expensive for what you’re getting:

  • jordan

    can they have fruit from fruit cups

  • Kaylee Boo

    Put it in a toilet paper tube

  • PnP

    Wow! I had a guinea pig that died “mysteriously” a year ago… and now I know why! I fed it 2 bananas every week! Thank you SO much for creating this blog!! Now my other two piggies can live longer, knowing that they can trust what I feed them. Also… what are some good (and safe) toys to create for my pigs?

  • Hi, PnP. Here is an article we wrote about toys for your guinea pig:

  • debra

    can guinea pigs eat juniper berries?

  • debra

    I have a small pets bed that I have made up for my guinea pigs and I fill it with sweet timothy hay ..there male guinea like to lay it in and eat away

  • No, guinea pigs cannot eat juniper.

  • Faith Walker

    I give my guinea pig reddish and he likes it never had a problem before
