Accident-only pet insurance costs $10–$18/month for cats and $15–$25/month for dogs — roughly half the price of an accident and illness plan. The trade-off is significant: accident-only plans cover injuries but exclude every illness, including cancer, diabetes, urinary disease, infections, and hereditary conditions. For most pets, illnesses generate the majority of expensive claims.
This guide lays out exactly what each plan type covers, shows real cost comparisons, and identifies the narrow circumstances where accident-only coverage is genuinely the right choice.

Cost Comparison: Accident Only vs Accident and Illness
Rates below use identical settings: 2-year-old pet, mixed breed / domestic shorthair, mid-size U.S. city, $500 deductible, 80% reimbursement, $5,000 annual limit.
| Provider | Accident Only (Dog) | A+I (Dog) | Accident Only (Cat) | A+I (Cat) |
|---|---|---|---|---|
| Pets Best | ~$15/mo | ~$24/mo | ~$9/mo | ~$15/mo |
| Spot | ~$15/mo | ~$22/mo | ~$10/mo | ~$13/mo |
| ASPCA | ~$18/mo | ~$31/mo | ~$10/mo | ~$16/mo |
| Figo | ~$14/mo | ~$22/mo | ~$8/mo | ~$18/mo |
| Healthy Paws | N/A | ~$40/mo | N/A | ~$25/mo |
| Trupanion | N/A | ~$70/mo | N/A | ~$40/mo |
The annual price difference between accident-only and A+I at Spot for a dog is approximately $84/year ($180 vs. $264). That's the premium you're paying to cover illnesses — which is far less than the cost of a single illness claim.
What Illness Claims Actually Cost: What Accident-Only Misses
| Condition | Covered by Accident Only? | Typical Cost | Species |
|---|---|---|---|
| Urinary blockage | ✗ (illness) | $750–$3,000 | Cats (male cats especially) |
| Cancer treatment | ✗ (illness) | $5,000–$12,000 | Dogs and cats |
| Hyperthyroidism (annual management) | ✗ (illness) | $800–$1,200/year ongoing | Cats 10+ |
| Chronic kidney disease management | ✗ (illness) | $600–$2,000/year | Senior cats |
| IVDD surgery | ✗ (hereditary illness) | $4,500–$7,000 | Dachshunds, Corgis, French Bulldogs |
| Hip dysplasia surgery | ✗ (hereditary illness) | $3,500–$7,000/hip | Large breed dogs |
| Diabetes (ongoing insulin + monitoring) | ✗ (illness) | $1,000–$2,500/year | Dogs and cats |
| Skin allergies (ongoing treatment) | ✗ (illness) | $500–$3,000/year | Dogs especially |
| Ear infections (recurring) | ✗ (illness) | $150–$500 per episode | Dogs with floppy ears |
| CCL tear (ligament) | ✓ (classified as injury) | $3,500–$7,000 | Dogs |
Note on CCL tears: Most providers classify CCL (cruciate ligament) tears as accidents/injuries, so they are covered under accident-only plans. This is the one major expensive claim that accident-only handles — but it only applies to dogs, and only if the tear is traumatic rather than degenerative. Some providers classify a gradual or degenerative CCL tear as an illness.
When Accident-Only Pet Insurance Makes Sense
Accident-only coverage is appropriate in a narrow set of circumstances:
- Very tight budget with a young, healthy pet under 2 years old. A kitten or puppy under 24 months has a near-zero probability of developing cancer, diabetes, or most hereditary conditions in the near term. If your budget truly cannot support $22+/month, accident-only provides a safety net against the most expensive acute injuries (emergency surgery, trauma) at a lower entry cost. Upgrade to A+I when budget allows.
- Bridge coverage during a gap in A+I coverage. If you're switching providers or between jobs and can't afford A+I temporarily, accident-only prevents a total coverage gap.
- Supplemental coverage alongside a second policy. In rare situations where an employer group plan covers illness but has poor accident coverage, accident-only from a second provider can fill the gap.
Accident-only is NOT appropriate for:
- Cats of any age — urinary blockages, hyperthyroidism, and CKD are the most common expensive cat conditions and all are illnesses
- Purebred dogs with known hereditary risks (Dachshunds, French Bulldogs, German Shepherds)
- Any pet over age 3 — illness probability increases substantially after this age
- Anyone who wants to avoid a $5,000+ out-of-pocket bill from cancer or chronic disease
The $84/Year Question
At Spot, the difference between accident-only and A+I for a young mixed-breed dog is roughly $7/month — $84/year. That $84/year buys coverage for:
- Any cancer diagnosis (expected cost $5,000–$12,000)
- Diabetes management ($1,000–$2,500/year)
- Chronic kidney disease management ($600–$2,000/year)
- Every illness listed in the table above
The break-even calculation is straightforward: if your dog or cat develops a single significant illness in its lifetime — which 1 in 3 pets do in any given year according to veterinary industry data — the $84/year difference pays for itself many times over from the very first claim.
Which Providers Offer the Best Accident-Only Plans?
| Provider | Accident-Only Plan | Starting Price (Dog) | Annual Limit Options |
|---|---|---|---|
| Pets Best | Accident-Only BestBenefit | ~$15/mo | $5,000–Unlimited |
| Spot | Accident-Only | ~$15/mo | $2,500–Unlimited |
| ASPCA | Accident-Only | ~$18/mo | $3,000–Unlimited |
| Figo | Accident-Only | ~$14/mo | $5,000–Unlimited |
If you do choose accident-only, use a provider with at least a $5,000 annual limit (avoid $2,500 accident-only plans from Spot — a single emergency surgery can exceed that). Pets Best and Figo offer the best accident-only plans with adequate limits at the lowest price points.
Frequently Asked Questions
Is accident-only pet insurance worth it?
For most pets, no — the $84–$180/year premium difference between accident-only and accident and illness coverage is far less than the potential cost of a single illness claim. Accident-only makes sense only for pets under 2 years old when budget is severely constrained. For cats of any age, accident-only is particularly poor value since the most common expensive cat conditions (urinary blockage, hyperthyroidism, CKD) are all illnesses.
What does accident-only pet insurance cover?
Accident-only plans cover: broken bones, lacerations, bite wounds, trauma, foreign body ingestion, toxin ingestion, eye/ear injuries from accidents, burns, and in most cases ligament tears (CCL/ACL). They do not cover any illness, hereditary condition, cancer, chronic disease, or infection — regardless of cost or severity.
Does accident-only cover CCL (cruciate ligament) surgery?
Usually yes — most providers classify CCL tears as accidents/injuries. However, some providers require the tear to be traumatic (sudden onset) rather than degenerative (gradual). If your dog has been limping for weeks before the diagnosis, the provider may classify it as a degenerative illness rather than an accident. Check your specific policy language before assuming CCL coverage under accident-only.
What is the cheapest accident and illness pet insurance?
For dogs: Spot (~$22/month) and Lemonade (~$22–$26/month) for young mixed breeds with $500 deductible, 80% reimbursement, and $10,000 annual limit. For cats: Lemonade ($11/month) and Spot ($13/month). These prices are close enough to accident-only plans that accident-only rarely provides meaningful value for an informed buyer.
