Oh he's lovely!
Pet insurance: You need to make sure that it's lifetime cover. If they offer to cover a certain amount of fees 'every 12 months', they're telling you that you are renewing your insurance every 12 months and usually, anything you claimed for in the previous 12 months is now classed as a 'pre-existing condition'.
If you get a lifetime policy, then unless you have a break in your insurance (DO NOT DO IT), they will keep covering everything that was not pre-existing before the first day that you took a policy with them.
Eg.
'Every 12 months' cover to £4000:
1st year: Ear infection - abx, clean outs, operation, etc; broken leg £4500 - all bar £500 covered.
2nd year:Limit returns to £4000, but ear infections & leg related issue are pre-existing, all else covered. Ear infections return, Stomach condition declared - lots of investigations; £5000. Ear infections excluded, all costs of Stomach conditions covered up to £4000.
3rd year: Limit returns to £4000, but ear infections, leg related issues and stomach conditions are excluded.....
'Lifetime':
1st year: all covered bar £500
2nd year: limit returns to £4000, all covered
3rd year: limit returns to £4000, all covered
That's the difference.
