Rabbits arn't for everyone, but I love them and think they make good pets.
What are the pros and Cons of owning a bunny?
Pros: They are fun to watch, some can be friendly and develope bonds with their owners. They can be litter box trained and are smarter than most people give them credit for.
Cons: They can be very expensive. They need unlimited hay and fresh veggies. They must go to an exotics vet which is more expensive than a normal dog and cat vet. They should be spayed or neutered to make the best possable pet, and to prevent health and behavioral problems. They are not always friendly, you have to really earn their trust before they'll really enjoy spending time with you and some of them never really learn to enjoy hanging out with humans.
are they social do you need 2?
Yes they are social. I would recommend getting two especially if you don't have a lot of time to spend with them. However, bonding can sometimes be difficult and time consuming, and doesn't always work with the rabbits you'd like it to work with. It's usually best to let them pick out their own partners instead of picking for them, or to adopt an already bonded pair. Single rabbits can be happy too, but I personally like to keep them in at least pairs.
how big does a cage have to be to properly fit them?
Even dwarf breeds should get large cages, because they like the room to move around and play. Most, if not all, of cages sold in pet stores are too small. You could look into building your own, NIC cages are popular. Even with a large cage, they should get at least a few hours a day outside of their cage to get exercise.
i looked this up online and it said they dont like to be held, there ground dwelling animals is this true?
Yes it's true. Most of them don't like to be picked up and held. There are times when picking them up could be necessary, but in general I always try to interact with them on the ground.
and lastly , what are some common diseases/illnesses bunnys can get?
Cancer is very common in unspayed females. You also have to look out for GI issues. If a rabbit doesn't eat for a period of 12 hours or more, it should be considered an emergency. Some develope teeth problems and have to have their teeth regularly trimmed by a vet. I'd say things like abcesses, ear infections, and sniffles are also pretty common. Rabbits are prey animals, and so are good at hiding symptoms when they don't feel well. If you notice anything off, it's important to get them to the vet.
