We’re new to being rabbit owners, but the person at the shelter told us that adult rabbits should be eating Timothy hay, not Alfalfa hay. Younger rabbits need the nutrients in the Alfalfa, she told us, but that older rabbits are better with Timothy. Again, not an expert, but that’s the only tip we can offer.

Adult rabbits, especially since yours is slightly older should not be getting Alfalfa as it is too much calcium for them. Although, if she doesn’t eat her normal hay, which can be any other type, such as Orchard Grass, Timothy, Oat, Meadow, Botanical, etc you can use a teensy bit of alfalfa sprinkled in to entice her to eat it. You can get good quality hay at pet stores, farms, Tractor Supply stores, and even online. The two brands I trust the most is Oxbow which is in most pet stores, and Small Pet Select which is an online store that sells good hay. Hay should be 80% of a rabbit’s diet. Rabbits can also get 1/4 cup of pellets ( I use a brand called Oxbow for my pellets and hay btw) per five pounds of body weight. They can also eat about a cup of veggies a day or more depending on their weight. There is a list of safe veggies for rabbits on the website. You want to stay away from stuff like Iceberg lettuce or any other light colored veggies because those are not healthy for buns.
As for habitats, you want to make sure it has enough space for the rabbit to run around in and not feel as confined. They should have atleast 4 hours of free roaming around the house every day, but I would wait a little until your rabbit gets more used to her new surroundings. She will be generally shy and quiet at first. Before you start letting her out of her cage you want to make sure everything is bunny proofed and safe for her. When you start letting her out, make sure not to overwhelm her or be impatient with her. You want to let the rabbit come to you of course.
I think you have gotten down the basics already, just make sure to get her the right type of hay for her age asap. Also,you’ll want to find a rabbit savvy vet around your area so that they can tell you her age and check on her to make sure she’s healthy. Do you know if she’s spayed? If she’s older and not spayed yet, that’s something you might want to think about for the future. But for now, it’s best to focus on learning about the diet and care before getting to that. I hope this helped! (sorry its very disorganized so sleepy lol)

You might want to read all the informational pages on the website first, or check out HRS, House Rabbit Society to learn more about rabbits.

The BUNNY INFO section on this site has some pretty good basic information on how to care for a bunny. Rain has already mentioned most of it.

Your bunny is probably scared since it’s a new environment for her. It’s good to find a rabbit savvy vet to do a general check and see if she’s healthy. They will be able to confirm her gender (you’ll be surprised how many people get this wrong) and if she has any teeth issues etc.

If she’s in the cage 24/7, then it’s not really big enough for her to exercise. The run space should be big enough to perform binkies and zoomies (you could try youtubing and see what those are and you’ll know why she needs a bigger space). You could also always keep the cage door open and she will most likely explore once she feels comfortable enough.
