## What each tier covers

*Accident-only vs accident and illness*

| Covered | Accident-only | Accident and illness |
| --- | --- | --- |
| Broken bones, cuts, swallowed objects | Yes | Yes |
| Infections, digestive and urinary illness | No | Yes |
| Cancer, diabetes, allergies | No | Yes |
| Hereditary and congenital conditions | No | Yes (if not pre-existing) |
| Routine and preventive care | No | Only with a wellness add-on |
| Relative premium | Lowest | Moderate |

## When accident-only makes sense

- A tight budget where some protection is far better than none
- A young, healthy pet where accidents are the main near-term risk
- An older pet who no longer qualifies for new illness coverage by age

The trade-off is real: illness, not injury, drives most of the largest and most common claims, so accident-only leaves the biggest risks uncovered.

## Why most owners choose accident and illness

Cancer, chronic disease, and hereditary conditions are where bills climb into the thousands and keep recurring. An accident-and-illness plan is the standard recommendation for exactly that reason. Where a wellness add-on fits on top is a separate question - it bundles routine care but is not catastrophe protection.

## Frequently asked questions

### What is the difference between accident-only and comprehensive pet insurance?

Accident-only covers injuries such as broken bones and swallowed objects but not illnesses, and it is the cheapest tier. Comprehensive - accident and illness - adds infections, cancer, diabetes, allergies, and hereditary conditions. The illness coverage is what most large claims rely on.

### Is accident-only pet insurance worth it?

It can be, when the alternative is no coverage at all. It protects against injuries at a low premium, which suits tight budgets or pets who no longer qualify for illness coverage. But it leaves out illness, which drives most big vet bills, so accident and illness is usually the better value.

### Does comprehensive pet insurance include routine care?

Not by itself. Comprehensive means accident and illness. Routine and preventive care such as vaccines and dental cleanings is only covered if you add a separate wellness plan for an extra premium.

### Which pet insurance plan should I choose?

For most dogs and cats, an accident-and-illness plan with a high annual limit gives the best protection. Drop to accident-only mainly for budget reasons or when age rules out new illness coverage. We help you compare the tiers for your specific pet at no cost.
