When a licensed vet clinic has a last-minute surgical opening, they discount it rather than leave the slot empty. We alert you first.
We'll alert you the moment a discounted slot opens near you.
How it works
Your email, your city, your pet. No account, no app, no credit card — ever.
When a nearby verified clinic posts a last-minute discounted opening, you get an email before it goes public anywhere else.
Lock in your spot with a small deposit. The rest is paid at the clinic on the day — no surprise charges.
The model
Staff are paid regardless. Equipment is booked. A cancellation that goes unfilled is dead overhead — clinics are motivated to fill it fast.
Same licensed vet. Same equipment. Same standard of care. The price drops because the slot is last-minute — nothing else changes.
Alerts go to our list before the slot is posted anywhere else. Being signed up is the only way to know about it in time.
"Spay and neuter procedures often range from $300–$600 at full price. Last-minute clinic openings are one of the few legitimate ways that price comes down significantly."
Questions
Yes. Empty Slot is completely free for pet owners. We earn a small fee from the clinic when a slot gets filled — you never pay us anything.
Every clinic on Empty Slot is a licensed veterinary practice. We verify credentials before any clinic can post openings. The discount is on timing, not on the quality of care.
A last-minute cancellation leaves staff paid and equipment ready but no revenue coming in. Filling that slot at a discount is still better than leaving it empty. You get a lower price; they cover their costs.
Click the alert, review the listing, and secure the slot with a small refundable deposit (typically $25–$50). The discounted price is locked in at booking. You pay the remainder at the clinic on the day.
Deposits are refundable if you cancel more than 48 hours before the appointment. Each clinic's exact cancellation policy is shown clearly before you confirm.
