I once advertised Fat Tabby on SitterCity as it was free. I got one really great client from there and both they and I were lucky. After that SitterCity wanted more $$ to advertise in MY area – I was being advertised in the Central Valley. Rover, DogVacay, SitterCity, and Care.com – these are web software companies not pet (or baby) sitting companies. Anyone can be on there. Despite what they claim NONE of those sites properly “vets” a sitter. No one ever contacted me or asked me information. I didn’t have to fork out any money (a line that divides the pros from the cons – literally).
I only recommend that people go to Pet Sitters International (my professional organization) or the National Association of Professional Pet Sitters to find a sitter who is honest and reliable. When a sitter has taken the time and invested the money to be vetted, bonded, and insured you know they won’t do this. Your pets are worth the investment.
