my kittens ears.

Question
Hello,

Approx. 2 months ago I adopted a kitten from a lady who was trying to take care of a few local cats that had been abandoned by thier owners. A while before that I adopted an older cat from another lady who was dealing with similar issues.

Well when I got the kitten it was living in this lady's small barn/garage and it wasn't in the cleanest of conditions but atleast she was trying her best. Anyways, the kitten had very dirty ears so I went to the pet store and go a solution to clean it's ears. It's gotten better but I still have to clean them on a regular basis.
Now I've noticed the older cat is getting the exact same thing in his ears. I wonder if this is some type of ear mite? The dirt is very crusty and dark brown/black and builds up very quickly. They are both indoor cats by the way. What can I do to ride them of this? and can humans catch this?

Answer
no humans cant get earmites and take your cats to the vet for an ear cleaning and a 1 time treatment of ear mite medicine the ear cleaning should cost about 12 dollars each cat and your vet will most likely require an exam which can cost anywhere between 20 to 35 dollars each cat.
