My 5 week old kitten i shaving ear problems. I have an organic apple-cider vinegar solution that was given to me to put into her ears, but she only seems to gain temporary relief from that. Her ears are slightly red and this brown/black waxy stuff is present. Is this a sign of mites or could there be anther condition? Also, why is it when she gets stressed she seems to go to sleep (i.e. when cleaning her ears she'll panic and then she'll be sleeping)?
