I only used the free service. Even though Zeus found his way home on his own LostMyKitty.com was a great service. The account was easy to set up and the email and fax blasts saved me a lot of time and phone calls so I could spend my time looking for him and hanging up fliers. The ready made fliers was also great (also, saved me time instead of having to make my own). The flier gave a lot of information but kept it easy to read and it stood out. Losing a pet is a very stressful time and LostMyKitty.com provided great support. I did receive some promotional emails trying to get me to use the paid service but they are a website that needs to support itself.
