No 🙁 Milk is not safe. I would avoid probably all Vitakraft products.
OK thank you!!
What treats can I give my guinea pigs to teach them tricks?
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.
I give my gunnia pig ice burg lettuce and tomatoes and she has lived for 5 years
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!
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!
I have ecotrition Guinea pig food and it has small seeds is it safe and healthy?
To the designer of the Dangerous Foods List…This is the correct spelling of poisonous. Just trying to help 🙂
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 🙂
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!
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.
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!
i feed my guinea pigs green beans,carrots,brocolli,dandelion leaves and hay.
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. 🙁
Are the leaves of the Common Nettle ( Urtica Dioica) safe for guinea pig consumption? ( not all plants of this species have bristles that sting)
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.
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.
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:
can they have fruit from fruit cups
Put it in a toilet paper tube
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: https://www.happycavy.com/cheap-free-guinea-pigs-toys-cavy-will-love/
can guinea pigs eat juniper berries?
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.
I give my guinea pig reddish and he likes it never had a problem before
Hi, I was wondering if the pigs could have lemon tree leaves and stems. My potted tree is in need of pruning and I thought maybe my Lil pigs could have them as something different.
I have a guinea pig that is 7 years old and he LOVES red bell pepper. He eats it, a smallish piece, 2-3 times a week. I have had other piggies who have also eaten it and it hasn’t been a problem. I highly doubt that your guinea pig died from the red pepper, although you might want to consult with a reputable veterinarian who treats guinea pigs for more answers. We had a guinea pig who died of lymphoma, who went downhill in a matter of a few days before he died-your guinea pig may have been hiding an illness that he couldn’t fight anymore.
Alfalfa hay shouldn’t be given to adult pigs, the calcium content is too high.
bell peppers are good for them (remove seeds though) the ones that are not good are chilli peppers ect
they aren’t giving the bell peppers to the guinea pigs ALL the TIME.
I’m a new piggy owner. Can I feed him green onion? Once in a while.
Hi, Sarah, guinea pig cannot eat onion of any kind — including green onion.
Okay. Thank you for quick response. I appreciate it and so does Chewy.
no , any type of onions is poisonous for them
Can I give my pigs butternut squash n salad onions ?
Can guinea pigs eat the flesh of a tomato?
Yes, guinea pigs can eat the flesh of a tomato. But tomatoes should be fed sparingly, as they are high in sugar.
My one loves iceburg lettuce. But doesnt drink alot of water. So me washing it and feeding her that should be ok?
Iceberg does have a lot of water content, so it would definitely hydrate her. But it’s concerning that she isn’t drinking water. Is it possible she’s drinking water but you aren’t noticing? You could use the “measure and mark” method to find out how much water she is actually drinking:
“For water, mark a line on your guinea pig’s water bottle in the morning, and check how much is gone in the evening.”
Sometimes when a guinea pig has a UTI, they may not drink water from a bottle because peeing hurts, and reducing their water intake reduces their need to pee. You may want to monitor her closely to ensure she is healthy: http://www.guinealynx.info/uti.html
I gave my guinea pig a little bit of fried veggie nugget. Will he die?
Watch your guinea pig carefully — make sure it’s drinking water and eating normally. Check it’s poops to ensure they are healthy in appearance. Find a cavy-savvy vet in your area and inquire about their emergency care services so you have contact info on hand before something happens. And, in the future, don’t feed your guinea pig anything it shouldn’t be eating.
I feed my guinea pigs some cheap deer feed is that safe for them
No, of course not.
