Aside from the fact that I feel like the worst, most irresponsible cat owner, ever, is there any hope of getting a policy that will cover his condition, should he need treatment, in the future? The vet only found a slight trace of a murmur but as it's on his notes, we have to declare it. He has no symtoms, is not being treated and is just being monitored (every six month check ups)
From what I've found, no one will insure pre-existing so I'm basically waiting for my cat to get ill and then be told I can't afford to keep him well / comfortable / alive.
Of course, there's a chance he could be fine but I'm a worrier

Also, does anyone know the rough costs of possible treatments? Beta blockers, scans etc?
Thanks everyone.
