I think a litter of my kits has fur mites but I'm unsure. They are missing fur on there foreheads..the skin is red and looks like the have dry skin. I have never had fur mites before.
It could be a mite of some kind. Most types of mites (including mange mites) respond to treatment with ivermectin, though you need to repeat the treatment at 10- to 14-day intervals to effect a cure.
