Honestly, the answer is no.

Yes, some people seem to keep the two together without any obvious problems, but I think you also need to look below the surface. Small animals are exceptional at hiding signs of stress and distress, so most people wouldn't eralise if there pets were unhappy with their situation. And most people's idea of "success" with small pets is that live for a couple of years. I would be curious to know how many of these rabbits and guinea pigs actually live contended and full lives.

Another point to consider is that both rabbits and guinea pigs are social species - they need the company of their own kind. As totally different species they can not communicate with eachother, and interact in totally different ways.

And of course the biggest problem is the risk factor. As the others have said, rabbits can easily kill a guinea - either through carrying certain diseases or physically, even by accident.

You will find that whilst some ignorant pet owners say its okay, the "experts" and animal welfare groups all agree that they should not be housed together. This includes the people on this site and the other guinea pig links from here, the RSPCA, Blue Cross, the rabbit welfare association and fund (part of the British house rabbit group), Rabbit Rehome etc.....

Obviously the best option would be to get another rabbit - it doesn't need to be a large one. Of course, this will only work if you actually have enough space - would you mind me asking how much space you actually have available?
