I am using oral terbinifine and twice weekly shampoos with KetoHex followed by a LimePlus Dip for our two kittens that have been diagnosed with ringworm (confirmed by my daughter and me getting ringworm and a culture). I have been doing the shampoo/lime dip for two weeks and they have been on the oral terbinifine for one week. Is this supposed to get worse before it gets better? At first, there was only one or two tiny (hard to find) spots on the girl. Today, she is crusty all under her front legs (armpit area), on front legs, and on her chest (under her neck). The boy had a few spots, but he is now really crusty all in the same areas (chest, under front legs, and on front legs). His left ear is also very flaky. Their skin almost feels hard to the touch. Is this normal? I'm taking the for a follow up appointment tomorrow. It seems like they have gotten worse in the past two days. Help!!
