We just got a skin scraping done on our rabbit and they found 2 mites. Only two. These things are pretty easily missed. Going to burn everything with fire (not really). Signs of mites include scratching and dandruff/dryskin. They are cross-species. I know cats can get them. Maybe dogs. They can bite humans, though they can’t live on our skin for very long. I don’t have any bite marks, but my girlfriend who spends more time with that particular rabbit has many all over her stomach. Check yourself and other household members for little red bumps.
If you have multiple rabbits and one shows positive you should assume they all have them and get them all treated. We were given Revolution, a cat topical liquid thing. You’ll want to at least vacuum every part of the house and furniture. Wash anything that can be washed that they frequent. Also wash your bedsheets and clothes. Begin changing their hay every night. Things like that.
