Theoretically, it is possible, and some have done this in the past. You need to be careful because rabbits can bully guinea pigs, and pigs require a diet higher in Vitamin C. If you are going to do it, I would still house them separately, and if they tolerate it, allow them to have supervised playtime.

Obviously, the rabbit would still have to be spayed or neutered to decrease hormonal/aggressive behavior. People think that they don’t have to spay/neuter since there is no chance of pregnancy between a rabbit/guinea pig, but it still has to be done for their safety.

My two piggies have a condo in the bunny room, they’ve all been together for several years now. I have the sides of their colorplast cut low enough so they can watch the bunnies. I’ve let them out to play in the bunny room with no problems, they all touch noses and go about their business.

In cool weather I let them play in the outside pen while the bunnies are out and it’s really fun to watch. The piggies graze like little cows and stay close to the buns. Piggies like to play follow the leader and the bunnies don’t quite know what to do when the pigs line up behind them and start squeaking but after they nose them to see what’s going on, the buns just hop away with the pigs nose to tail right behind.

The piggies like to hide and it’s funny to watch them try to burrow under Pringles while she’s stretched out in the grass for a nap.

They shouldnt be housed together.

before i knew better, i housed a guinea pig and a rabbit together. after the RABBIT started loosing drastic weight, i realized the guinea pig wasn’t letting him eat. it’s usually the other way around- the rabbit won’t let the piggy eat.

having both in the same room, maybe even letting them play occasionally (supervised), would be fine. housing them together, though, isn’t a good idea.

Different people have had different experiences, and some buns will tolerate a guinea pig, some will not. I don’t want to say flat out, “Absolutely not!” because many people have done this successfully, including one of our Forum Leaders.

I would not get a guinea pig with the expectation/requirement that they must be housed together. It might work, it might not. Also guinea pigs do not potty train the way a rabbit does, so you will be going thru much more litter than you would with only a rabbit, and the rabbit might even lose its litter habits because it is housed on litter all the time, rather than having a dedicated litterbox. Also, guinea pigs require a very, very large horizontal space because they do not jump.

Beka’s right, guinea pigs don’t potty train and they’re a lot messier to take care of. I definitely wouldn’t house them together. When I let mine out in the playroom I have to mop the entire floor afterwards.

I help at a guinea pig rescue and they do not recommend housing rabbits and guinea pigs together. Rabbits can unintentionally harm a guinea pig if they kick them when they hop around.

And everything else that has been said – litter box training – cannot be done with a guinea pig even if they are neutered and it’s true that a rabbit may lose their litter habits if housed with another species.

And the bedding for a guinea pig may not be the most absorbent litter for a rabbit, in other words, aspen bedding while rabbit safe and guinea pig safe may not control odor as well as some more appropriate litter for rabbits like wood stove pellets or Yesterdays News.

It’s really not ideal for either species to be bonded. Better to bond a piggy with a piggy and a rabbit with a rabbit.

I heard that having a rabbit and guinea pig together was like putting two people together who couldn’t speak the same language (except obviously the people would be the same species so they would adapt). They just can’t “speak” to each other or understand each other and therefore, while they can coexist in some cases, it doesn’t replace having a real companion of their own kind.

*hand up* I’m the forum leader who did that!

It was under these circumstances:

1) It was for my senior palliative bunny (i.e. it was not going to be a long term thing)
2) I knew my bunny would not hurt him as I knew his personality, he was three pounds, blind and very gentle. Also hardly mobile so really not going to be doing any kicking
3) If it didn’t work out (For either) I would have returned the pig
4) My rabbit needed a buddy to be with him, he was lonely but he was also again-old, blind-a serious bonding with a rabbit at his age and state would not work.

So I basically used the guinea pig to keep him company, and I knew neither was a danger to the other, as senior palliative blind bunny and baby guinea pig probably not going to fight. That said I spent about five hours a night in their with them to ensure they were getting along. And they were, it worked beautifully.

Would I do it long term? Nope.
Would I recommend it? Under similar circumstances…maybe. But not in general certainly not.
What do my other bunnie think of my pig? Don’t like him.
What do I have now? Two stinking guinea pigs

(vv you can see them together below in my signature)

I have four male guinea pigs at the moment. I have let some have floor time and my bun Gabby was not enthused about them running around in “her” living room. She proceeded to thump and sulk around the room. I was in the room the whole time as I was cleaning the pig’s cage while they were playing in the floor. I would not have left the room with them all out together as I know one good bunny kick could kill or seriously hurt my pigs.

One time I went to adopt a guinea pig from an animal shelter 2 1/2 hours away and after filling out the paperwork on him was told he could only be adopted if I took his best friend a rabbit along with him. I was so upset and couldn’t bring the piggy home with me. I tried my best to explain how the piggy could be accidentally hurt by the bun but they refused to listen to me.
