This is article I reference a bit regarding fur loss. http://www.bio.miami.edu/hare/furloss.html#furmite  Scroll down to mites and fleas.
I did read somewhere that it’s normal to have a small population of mites on a healthy rabbit but when it’s health is compromised, this population can grow and become a problem. That is when you start seeing fur loss etc An underlying condition could also be a factor in this buns aggression.

Cats & dogs can carry fur mites without being effected by them. So that’s another way they can enter the home.

Did it start to effect other areas beside top of head? Is the treatment working?

Edit: Also  http://www.medirabbit.com/EN/Skin_diseases…urmite.PDF  This one covers treatment and treating the home.

Thanks for that link Jersey, it answered my question about the mites my pigs have

If I am understanding this correctly, he could have had the mites for weeks before we noticed.

Yes, i think so. Fur mites don’t always cause fur loss or itching so they can be infested without obvious symptoms at first, then as it progresses more symptoms show. I believe rabbits in general can have fur mites that just live on the skin – like we have our own variety of bacteria etc that lives on our skin. The immune system keeps infestation under control. When a rabbit is under stress, sometimes going thru a shed, suffering from some other health issue, the fur mites numbers may increase as the immune system is occupied elsewhere (or compromised)  & so not keeping the numbers under control. This is my understanding anyway.

Edit: Just want to add…I just read what Lintini suspects her piggies have in her thread. She added the paragraph about burrowing mange mite from the first link above.  It is less common in rabbits but there was mention of some cases where rabbit became more aggressive when suffering from that mite infestation.  I was of the mind that with your bunny it was like:  mystery health issue=aggression/stress=fur mite issue  – but now i can see with some types of mite and some bunnies the mite issue may cause aggression…   Hope you see some improvements soon.

Hmmm all I know about mites is: that they can be hard to treat, and that there are several different types… So I don’t know alot-Looks like the link Jers posted is really good though Keep us posted on recovery {{Healing Vibes}}
