Rabbit skin problems

Question
Hi i have a 6 month old holland lop. I am currently treating him with revolution for a small issue with fleas. I have noticed this last week or two a hairloss spot on his ear. it doesnt look scaly its just smooth natural skin do you think that could be fromitching? or most likely ringworm? or maybe an inner ear issue? i did also notice he does have some build up in his ears it kind of looks like wax because it has a yellowish tint but not sure? i do work at a pet specialty store that i could of brought it home to him? also i usually have been checking his genital area because he keeps getting his kitty litter stuck to it and i noticed tonight that he has a small kind of oval shape possibly some pus filled bump. its not big its rather small but noticeable im thinking its pus filled because it has a yellowish top i was wondering if you possibly know what this could be? maybe a small abcess? i am going to make an appointment but thought maybe i could get an idea if theres anything possibly going on?
thanks kailey

Dear Kailey,

The flaky skin and waxy ear gunk could be the death of mites from the Revolution.  Fur mites (Cheyletiella) and ear mites (Psoroptes cuniculi) may have been in residence, but then were killed by the Revolution, and their remains and crusts are now falling off.  Groom bunny gently, as you normally would, but be very careful with the ears, as they are sensitive.  Please read:

You can find a good rabbit vet here:

to help with this recovery.

The vet should have a look at the possible abscess.  I can't judge without seeing it.

The butt-ball problem is pretty common in rabbits who have cecal dysbiosis.  Please read:

and be sure he's on a healthy diet, which will prevent this problem:

Be sure you're not using clumping or clay cat litter.  Use organic type litters, such as pelleted recycled paper or pelleted sawdust, covered with a thin layer of soft hay.  This will also promote good litterbox habits.

I hope this helps.
