I unexpectedly became a bun mom after watching my friends rabbit for almost 3 months while they were overseas. I had ivy had experiences with cats and dogs as well. It's a big learning curve. First be ready for GI Stasis. Their digestive system will show down it stop and they will be in pain. They will stop eating and pooping. You want your bunny to be eating lots of hay and pooping a lot. Here are the first to try while waiting to see a veterinarian: Here is a video: https://youtu.be/LbyC6CWbm5M?si=pzwHmdia0iHyl-Wu So go get yourself baby gas drops and emergency rabbit feed like: https://www.amazon.com/Pet-Rabbit-Emergency-Timothy-Recovery/dp/B07Z7BJTXR/ref=ast_sto_dp_puis There is another popular one named Critical Care. And make sure you have a couple syringe feeders around as well in case one gets lost/ damaged. The video doesn't talk about the emergency feed but your rabbit will not be eating and it's important to keep their digestive track moving so you will want to give it to him. Keep the emergency feed in the freezer to extend its shelf-life because hopefully you will rarely need to use it. I was so lucky i was watching the rabbit for a while already, so when he stopped eating I knew something was off, otherwise I would have assumed he was stressed in my home and needed some time to adjust. Turns out GI Stasis can get bad fast and they can die from it. Rabbits require an exotic vet and no one was available until the next day. I googled some info and watched that video. I was very lucky the veterinary clinic at least had emergency feed. I would not have known what to do to feed him. Luckily he responded after the third time I gave him the gas drops and belly massages, and I was able to cancel his appointment. One thing I wish I learned while he was still young is to train him with the feeding syringe by feeding something that would be a treat to him with the syringe. Like a tiny bit of mashed banana mixed with a bit of water to get it to go in the syringe. If you ever give him banana it should only be a small piece... maybe like a one inch piece depending on the size of your rabbit. My friend's family kept the rabbit in a cage and her daughter took him out for an hour or two a day to play. I learned that rabbits are supposed to be free-roaming, but he wasn't my rabbit, so I spoke to my friend and I got him a playpen to attach to his cage so he would have more room. I was going to give it to her when I returned him. Once he did become mine I still wasn't sure I was going to let him free-roam. He wasn't neutered yet, and rabbits poop to mark their territory when not neutered, so he was pooping outside his litterbox. After I got him neutered I let him free an hour a day, then eventually 2 hours, up to letting him out so long as I was home. Then eventually he was free all the time. He still has his cage and playpen that he goes in and out as he pleases. Rabbit proofing your home is a thing. They like to chew on cords, cardboard, wood, even my phone cover! If you have a rabbit that likes to be picked up you are one of the lucky ones. They generally don't like it. Oh and rabbits can sleep with their eyes open. I used to wonder why my rabbit would just sit in a random spot staring into nothing and not moving. Turns out he was just sleeping lol. Here is a feeding chart my vet gave me
