I was extremely disappointed with Pets Best Health Insurance. My cat is 15 and all of his claims except one was denied because of an "existing condition". He did not have the existing condition at the time his policy started. The one claim that was not denied was applied to the deductible. Claims took an extremely long time to be determined. The last one I filed said I'd have a response in 4-5 days. Well, it was actually about 30 days before it was approved. Every claim I submitted contained the doctor's evaluation, yet Pets Best had to go to the vet for more information. Convoluted process with no customer service attributes.
