My kitten is 3 months old and she has had earmites for sometime now. I went to petland discounts and they suggested I use hartz earmite drops. She would meow really loud like if she was screaming when I would put them in. She would not let me touch her ears and her ears became really dry and red. She developed mucous and this dryness in her ear it became hard and started peeling. She had crust around her ears and inside. The crust was very thick and hard. Her ears are peeling and her head was twitching. Since I stopped using them she is better playful back to her old ways. Marilyn is also more happy. Dont use Hartz Product it is horrible she is still a baby and it hurt her I just wish I could of found this website before I used the product.
