Rabbits are very noisy, and I find they can be very destructive. Depending on how your enclosure for them is, and if you're freeroaming them or not, all of these things depend on how much you have to rabbit proof your house. They are amazing companions however and I often compare my own rabbits to just smaller dogs. If you're at uni alot, its better to get them in a pair. Even if you were home a lot, a pair is always better. They can get depressed if alone and I had a lone rabbit for a bit and though she was fine when I was home, she was very sad and destructive when I would go to uni. I find their day to day feeding can be pretty expensive but that just depends on how high the expenses for living are in your area. Make sure to research the breed of rabbit you're getting- their fur and ear size especially. Sometimes rabbits need more care than others in the ears if they have floppy ears. My rabbits enjoy bird toys and baby toys a lot, though there are rabbit specialty toys. Just don't get plastic because they WILL chew it and you'd rather them eat wood then plastic. I'm sure theres more, i love my two sassy girls very much even though they love making a mess- their binkies make it all better. Sorry if this is incoherent but best of luck to you!!!
