According to what I know pets cannot contract the scabies mites. However they get infected with a similar form of mite that they can pass on to you which will cause itching and iritation, but is not permanent like the scabies mite. In this case the mites will die after a few days, while the scabies mites can reproduce and will not subside until treated. I think you really need to know more .

If the mites are scratched off they may hatch in 3-5 days depending on when they were laid. It's unlikely eggs are off a host since they are laid in burrows in the skin.

steroid creams, antihistamines (such as Benadryl), and, in severe cases, steroid pills can be used to relieve itching, but they do not kill scabies mites. Benadryl does not kill the scabies mites.
