Yes, I second Stray Hares, some rabbits are down right destructive!
Here is something I wrote comparing the two a while ago.
My experience and opinion as a long term rabbit and guinea pig owner, I have had guinea pigs on and off for 20 years and rabbits for 13, is that rabbits are much more difficult to care for than guinea pigs.
1. Rabbits are smarter than guinea pigs. There are some very smart guinea pigs out there but on average I believe it is safe to say that rabbits are smarter than guinea pigs. Rabbits can be trained to do tricks and use a litter box. Most guinea pigs simply cannot do this.
2. Rabbits are mischievous animals. You put up a blockade they spend the next half an hour trying to tear it down. They know there must be something good behind it! Like nummy wires to chew! For guinea pigs you put up a blockade and they just accept that is where their space ends. I have one guinea pig that will chew or try to push his way through but if he doesn't make it in the first few tries he gives up.
3. Rabbits chew!! Some more than others but nothing is safe from rabbit teeth. Carpet, wires, base boards, whatever it is most rabbits need to be trained NOT to destroy it. Guinea pigs generally leave these things alone. They just do not have an interest in gnawing a hole through your drywall.
4. Rabbits need more space. They are bigger and build differently. They also need enough space to stand up and it helps if they have multiple levels to jump on. Guinea pigs just need one flat continued space. They don't seem to really enjoying sitting on top of things but they can use multiple levels.
5. Rabbits need more attention than guinea pigs. Rabbits seem to be more sociable towards humans than guinea pigs. They need and want attention from their owners. Most guinea pigs only crave human attention if that human comes bearing food. Out of all the guinea pigs I have had over the years only 3 sought out human attention if you didn't have food.
6. Guinea pigs need a guinea pig friend, rabbits can be happy with just a human friend but do better in pairs. If you work, go to school or are gone for long periods in a day a companion is a must for a rabbit.
7. Rabbits smell more than guinea pigs. Something about rabbit urine just smells worse than guinea pigs. More ammonia probably.
8. There is no such thing as guinea pig proofing your house. For free time guinea pigs will be happy running around your kitchen or in a blocked off area elsewhere. They do not need free range or a whole room just a big space for them to run around and play. Rabbit proofing is a whole house or room undertaking and for some rabbits it can be a constant battle as the rabbit figures out how to undo your rabbit proofing and you need to out think the bunny.
9. If I were to rate the level of care a guinea pig requires on a scale of 1-10 (10 being the most care, 1 the least) I would put them on a 4.5. They need daily attention and require a special diet, they require a big cage that needs daily cleaning but they are still relatively easy to care for. They do not require training and if you are busy one day and can't spend much time with them they are still pretty happy being guinea pigs all on their own.
10. If I were to rate the level of care a rabbit requires on the same scale I would put them at 7 or 8. Rabbits require all the same things as a guinea pig plus training, free space, rabbit proofing, toys, neutering and other vet care, etc.
The above list is my personal experience and opinions on rabbit care vs. guinea pig care or at least the biggest differences.
