Can your brother not remember taking tango in for anything similar?
how strong the link would need to be between symptoms and illness to denote a pre existing condition.
Alot of things can be down to having had flu at some point as its so common but its maybe also coincidental that many cats will be positive for certain viruses with no symptoms. Its down to each company how picky they want to be
Until you find out what history your vet has you cant really argue the case with m&s, if vets have noted symptoms of calici but not tested then they can use it against the claim if they so wish. Are they vaccinated? If not thats another way they could get out of paying up
The cost of treating an illness, injury or
behavioural disorder that happened or
showed clinical signs before your pet’s
insurance started.
If theres clincal signs of calici on his records then i would say the above is why they refused
This is where im glad to be with a company who will review exclusions, petplan can review after 12months if no further probs have been had. They even paid for simons tongue/mouth probs and biopsy this year even tho he started having mouth probs at a year old, he had a 12 month space with no issues so they lifted it
