^ Like the above user, but more specifically from that different forum post one user said this:
" The two things that worked the best for helping the overgrooming situation were:
1) Seagrass mats: My little boy became more fixated on pulling the pieces of the seagrass mats apart than the overgrooming
2) Giving a fixed schedule: The vet told me this can happen when the bunny feels unsettled, or nervous. There had been some changes in the house (new foster bunny) and Kramer was probably feeling a little unsettled, so for a few weeks, I fed him at the exact same time every day, played with him for an extended amount of time, and sat and petted him for a period of time at the same time every day.
After a few weeks of these two things the excessive grooming stopped!"
& About the bald spots they said -
"My boy Kramer still gives Juli some teeny bald spots from time to time, but the fur just is missing - the skin is not irritated and its very tiny spots so Juli does not seem to mind.
Also, putting ointment on the area or anything else could have the effect of the boy grooming the girl even MORE because he wants to "clean" her. Seperating the two just long enough for her to start getting her fur back is the best solution, but make sure they can still see each other, and lie next to each other by putting the separate cages right next to each other so that you don't interupt their bond. Once her fur starts to grow back, he will not be as concerned with this area! "
Hope that helps.
