I looked up Pet's Best but they don't cover congenitial issues. There is concern that Jens may have luxating patellas. My vet thought he had it slightly but wasn't sure on the initial exam, would definitely want that covered if it caused issues.

Purina has one that has fairly good reviews. They would cover Heidi (the 10 year old) but I am not sure it is worth the cost. Have to weigh that out.
