I don't know exactly but It must be in the thousands. I posted a sit that started in 9 days and within 24 hours I had 8 sitters apply, even from places 2000 miles away. The sitters we chose happily drove from Florida to Colorado in January to care for our pets for 2 months. We could not have been more pleased at how this all worked out.
