I agree with the others. Insurance in the states do not cover exotics so I recommend having at least $500 in savings as one trip could cost $300 if you need simple testing done (bunnies are not cheap when they get sick) and you don’t want to sacrifice your bunnies life because of poor financial planning on your part. You should also be taking your bun to the vet at least every 6 months for checkups as many can have teeth issues.
As for the bunny, it all depends on her weight and how much room she can move around. My new zealand (10 pounds) has 2 inches of soft foam padding covered by a shower curtain and fleece because someone likes to forget she is potty trained. it has really reduced her sore hocks, I suggest adding more padding, making sure her nails are trimmed at least once a month because bunnies in the wild are on grass which lets their nails sink into the dirt to relieve pressure on their hocks and put pressure on the front of their back feet. if a bunny doesn’t have a soft floor and long nails, they can not put pressure on the front of their back feet and leads to pressure on their hocks and sore hocks.
Make sure she doesn’t break the skin of her hocks as that can lead to infection.
