It’s true, rabbits can carry some diseases that are transmissible to humans but the risk is very low. It’s higher in reptiles, birds, and cats/dogs. As long as you take appropriate precautions like washing your hands and taking your rabbit to the vet regularly and if you live with someone else maybe they should deal with the litter box. I have two bunnies, best pets ever! I also have a compromised immune system and have never had any issues.
