| Criterion | Evidence to request | Why it changes the choice |
|---|---|---|
| Exact species eligibility | Written confirmation and policy definition | An uninsurable animal cannot benefit from the advertised plan |
| Illness and accident scope | Applicable policy form and exclusions | A low-cost limited benefit may miss the reason you are shopping |
| Treatment by the right veterinarian | Licensed-vet terms and claim requirements | Your chosen practice still needs to treat that species and provide records |
| Payout structure | Deductible, percentage or schedule, caps and sublimits | The advertised annual maximum may not describe payment for one illness |
| Medical history | Record requirements and prior-condition treatment | An existing problem may remain your responsibility |
Give these criteria priority in that order. If only one eligible offer is available, compare it with retaining the risk yourself and building an emergency reserve. One candidate does not become good value merely because the shortlist is short.
