Cat mange mites
The life cycle of Notoedres cati takes from 6-10 day to three weeks from egg to adult stage. Female mites burrow tunnels in the keratinized layer of the skin and lay eggs. In 3-5 days, the eggs hatch and the larva formed crawl on the skin surface. In turn, the larva burrow into the superficial layers of the skin forming small pockets and eventually molt into nymphs and adults.
