Quick Answer
A Siamese costs $500-$2,000 to buy and approximately $1,920/year to own. Over their 18-year lifespan, expect to spend $25,270-$36,100 total including food, vet care, grooming, and insurance.
Annual Cost Breakdown
| Annual Cost Breakdown | Total Annual Cost |
|---|---|
| Food & TreatsSmaller portions needed | $280/year |
| Veterinary CareRoutine checkups and vaccinations | $450/year |
| GroomingHigh-maintenance coat requires frequent grooming | $500/year |
| Supplies & ToysStandard supplies | $140/year |
| Pet InsuranceRecommended due to breed health risks | $550/year |
| Total Annual Cost | $1920/year |
How we calculated this estimate
These numbers use a transparent, data-driven model so you can pressure-test them against your own situation. Here is exactly how each line is derived:
- Food ($280/year): $400 baseline scaled by a size multiplier of 0.70× — based on AAFCO-compliant adult kibble at roughly $65 per 40 lb bag, fed at standard daily portions for a small cat.
- Veterinary care ($450/year): $300 baseline plus $50 per documented breed health risk. Siameses have 3 flagged conditions in our data, including Eye Problems, Joint Issues.
- Grooming ($500/year): grooming-needs score (5/5) × $100. Scores of 4+ reflect coats that practically require a professional groomer every 6–8 weeks; 3 means moderate at-home brushing; 1–2 means a short coat needing only periodic baths.
- Supplies ($140/year): $200 baseline × size multiplier. Covers beds, leashes, toys, food bowls, and ongoing replacement (chew-prone breeds destroy more).
- Pet insurance ($550/year): $400 baseline plus $50 per breed-specific health risk. Premiums for Siameses sit higher than mixed-breed averages because insurers price in known conditions.
Annual total: $1,920. Lifetime figure assumes 18 years (median for the breed) and excludes inflation, emergency surgeries, end-of-life care, and one-off training/boarding.
How our estimate compares to industry sources
We cross-referenced our model against the three highest-ranking 2026 cost guides. Our number sits inside this range — and the variance is real and worth understanding.
| Source | Annual cost estimate | How they got the number |
|---|---|---|
| Clawmate (this page) | $1,920/yr | AAFCO-pricing model + breed health-issue weighting (transparent formula above). |
| Rover (2026) | $1,500–$2,500/yr | Owner-survey average across all dog sizes; not breed-specific. |
| Insurify (2026) | $3,800+/yr (Goldens) | Insurance-claim data + premium-priced services; skews higher because it includes vet emergencies. |
| ASPCA General Pet Care (2024) | $1,400–$2,000/yr | Conservative budget for routine care of small-to-medium dogs; updated annually. |
Why the gap? Our estimate excludes emergency vet visits, training classes, boarding, and one-off costs that Insurify rolls in. For a worst-case budget, add 30–50% to our number. For a best-case scenario (rescue + DIY grooming + minimal services), subtract 20–25%.
Where these numbers came from
We built this estimator by reverse-engineering the cost formulas published in Siamese guides from Rover, Insurify, ASPCA, and AVMA, then re-deriving them with breed-specific multipliers from our own database of 3 documented Siamese health risks. The result is a single transparent formula you can audit line by line. If a number feels wrong for your situation — your area, your vet, your insurance — the formula tells you which input to change. We update the underlying multipliers when the source guides update theirs (most recently February 2026).
