Maybe it's this Michigan weather, skpaw.

My Kia's been itching up a storm. See my thread here. My vet is currently treating her for scabies.

Does it appear to be seasonal? Did Maggie start itching when the weather got colder?

I sincerely hope you don't have to put her to sleep.

Sometimes Kia looks miserable but I couldn't imagine putting her to sleep when she is overall healthy.
