Guinea Pigs/Guinea pigs/Rabbits breeding together

My male rabbir and female quineapig live with our birds and another female rabbit.  Yesterdday I was out feeding them all and right under my very eyes the male rabbit (Nacho)climbed onto Inga (the female g/p) he held her head down with his mouth and climbed onto her and away he went.  It looked the same as cats mating.  I was amazed.  I told my husband he went to look and there again was Nacho, after a second try.  I hope something comes of this, cos it proves that they do mate.  One thing we have never been able to do is dictate nature and which way it decides to turn.

Hi, I have 4 female guinea pigs and a male rabbit, this morning when I went to give them fresh hay, I found a baby in the hay (dead), I have checked on google what a rat's skeleton looks like but it doesn't look at all like the one i found with them, more like a guinea pig's because it was much larger than a baby rat's skeleton, I know because I have 2 rats too. And there is no way that a baby rat could have climbed into the enclosure because baby rats are very clumsy and can't climb as well as adults. And the enclosure has a roof and is more than 2 meters high.

So the only thing I could think of is that the bunny and the guiea must have mated. But now I have also read that is impossible since a bunny is not a rodent but a guinea, like a rat is a rodent.

I believe I have a GuineaPig/Rabbit crossbreed (Grabbit Pig)

I will post pictures.

It's possible.

I too am becoming a believe after my female rabbit had 3 babies, but 1 died, she had previously given birth 4 weeks before to the day and had 4 babies from which she was separated from the male rabbit before she had them, every time i let them out she would be in the pen and the male rabbit allowed to run freely and vice versa i usually put the guinea pigs in the same pen as the female rabbit then 4 weeks later along come the 3 babies the 2 that have survived are now 2 weeks old one of them is white and the fur is not like the other rabbit i guess time will tell how they grow and develop.

I am wondering if I have a guinea pig/ rabbit cross breed. I have a 4 year old female "guinea pig" which was got from a store where the rabbits and guinea pigs are kept together. Shes very large for a guinea pig, and has a completely different shaped body to that of my other guinea pig. Her facial features and eyes are more rabbit like and her ears are rather big, although still guinea pig shaped. Her back legs are slightly larger too. Basically she looks like a rabbit minus the tail and ears. I have been looking up guinea pig/ rabbit breeding and a lot of people have said about mysterious cases of pregnant rabbits/ guinea pigs when there is no other companion other than the opposite specie around. Is this possible that they could breed? And if they can, I do believe my piggy is a cross breed between the two!

But if you think about it carefully, a GP and a rabbit is in the rodent family. so it is possible.  It's like breeding a horse and a zebra.

Two different species can produce offspring.  Two different species cannot produce fertile offspring (for example a horse and a donkey can produce offspring (mule) but not fertile offspring.

That isn't true. Rabbit are in the order Lagomorpha, entirely different than rodents.

I have successfully raised and bred healthy guinea pigs since 1999. Altogether, I have owned 12 guinea pigs.

In one science fair I crossed two genetically diverse guinea pigs and accurately predicted the appearance of the offspring.
