Rabbits acutally aren'trodents (they belong to a species called Lagamorphs along with hares, rabbits, and pikas).
I would just maybe ask your friend for tips and a summary of rabbit owning. Also, look on the Rabbit 101 section and reference. The best thing to do before getting (if you do decide) is tobe knowledgable about rabbits.
Here's alink I'd advise looking at

Here's some basic things on owning a rabbit
Rabbits can live up to 10 years and beyond. They need a lot of work, and are a fairly easy pet to look after.Although easy, their is still a considerable amount of work in everyday rabbit owning.
A rabbits diet should be mostly ofa good quality grass hay (timothy, oat, blue grass, orchard ect). The next thingis pellets. Depending on the weight and age rabbitsshould get different amounts. You can also give some vegetables as a supplement to the diet
Rabbits can be litter trained and leashed trained. They should get everday exercise outside the cage to have a healthy body. Grooming is pertty minimum for most short haired breeds. Usually just an occasionalbrushing and nail clipping isgood. Rabbits are verys social and love to be played with. They also love toys.
Rabbits hide illness very well and usually theirappetite and output is key to figuring outif the bun is sick. For most rabbit illnesses, their appetite and poop/pee decrease.
I just posted basic info that came to mind. Feel free to ask any general question about health, diet, care,medical, breed, ect for more detailed information.
