A mobile spay/neuter clinic, staffed by the vets of tomorrow.

Final-year veterinary students must log surgical hours before they graduate. Shelters and TNR groups need thousands of cheap, safe sterilizations. Put a licensed high-volume spay/neuter veterinarian, three student tables and two RVTs in a fully equipped van, and both problems solve each other — with no building to rent.

Why it works

Everyone at the table needs what the other one has.

Students need hours

Fourth-year DVM students are required to log supervised clinical and surgical cases. Spay/neuter is the bread-and-butter procedure every graduate must be fluent in. A steady stream of colony cats is exactly the caseload their programs want.

Partners: UC Davis (incl. its shelter-medicine program), Western University DVM program; RVT programs at California community colleges

Shelters need volume

Reaching the 80 % sterilization line that collapses a colony means hundreds of surgeries per district. At private-clinic prices that's out of reach. A teaching clinic does it at cost.

Partners: the city shelter, local TNR groups, county animal services

Vets who love it

Plenty of licensed DVMs volunteer for TNR days already. Paying a supervising DVM a day rate turns goodwill into a schedule the city can count on.

Supervising DVM: licensed in CA, HQHVSN-experienced, carries the liability, physically in the van
A clinic day

From trap to release, under one roof on wheels.

7 AM

Intake

The TNR partner delivers trapped cats. RVTs check each one, log ID and weight, flag anything the DVM needs to see first.

8 AM – 2 PM

Surgery

Three tables. Students operate; the DVM moves between tables, verifies every ligature and closure, and takes over instantly if needed. RVTs run anesthesia and monitoring the whole time.

All day

Recovery

Climate-controlled recovery cages in the van. Rabies vaccine, microchip, ear-tip, and — for the mesh program — the breakaway collar go on before the cat wakes.

+24 h

Hold & return

Cats stay overnight at the partner facility while anesthesia clears, then go back to their colony — or into the 3-week acclimation crate at a new working-cat site. Every record lands in the dashboard.

The van

A fully equipped mobile spay/neuter clinic — and what it really costs.

Who pays for the van, and who ends up with it

Three ways, the city picks. (1) The city leases or provides the built-out Sprinter — city-owned, leased to the program for a nominal rate, or leased by the city in our name. (2) We fund it: the van goes on the grant stack (state, federal and animal-welfare funders like Best Friends, Maddie's Fund, ASPCA, PetSmart Charities, BISSELL) and the program carries the payment. (3) A sponsor buys it with their name on the door.

Either way the city ends up with it. When the contract closes out — the colonies aged out, the rats mapped and gone, the program done — the van is donated to the city and stays in service: an animal-services and public-health truck, a mobile clinic for the shelter, a service truck for whatever the city needs. The city never buys a second vehicle, and never loses the first one.

A long-wheelbase Mercedes Sprinter or Ford Transit built out as a Mobile Spay/Neuter Clinic (MSNC) is the industry standard for outreach. It is not a folding table in a cargo van: California's Veterinary Medical Board regulates a mobile clinic the way it regulates a building.

Surgical

Two to three surgical tables, surgical lighting, anesthesia machines with oxygen and monitoring (pulse-ox, ECG, temperature) per table, autoclave, instrument packs for a full day.

Prep & recovery

Prep sink with hot and cold running water, clipper station, climate-controlled recovery cage bank, separate clean and dirty zones.

Power & plant

Onboard generator plus shore-power hookup, fresh and grey water tanks, HVAC rated for a full cage bank in summer, medical-grade lighting and ventilation.

Compliance

DEA-approved locked storage for controlled anesthetics, medical-waste handling, VMB premises registration for the mobile unit, DVM-in-charge on file, insurance.

The people cost the van doesn't include est.

LineBasisPer clinic dayPer year (2 days/wk)
Supervising DVM (HQHVSN-experienced, carries liability)Day rate, or part-time salary$700–1,200$70,000–125,000
2 RVTs (prep + anesthesia)Hourly$600–900$60,000–95,000
Surgical supplies, anesthetics, vaccines, microchipsPer cat × 25$750–1,000$75,000–105,000

StudentsUnpaid — they're earning required hours; travel stipend if any$0$0–10,000
Operating total, ~100 clinic days ≈ 2,500 cats≈ $2,300–3,300≈ $220,000–360,000

That is roughly $90–145 per cat all-in, versus $300–600+ for the same surgery at a private clinic — and every one of those cats is also a rabies vaccination, a data point and a student's logged case. All figures are estimates for a grant narrative, not quotes. Full staffing on the budget page.

The grant stack

Roughly $300k for the van, $250–350k a year to run it. Here's who funds each piece.

Two things every one of these funders asks for

A 501(c)(3) applicant — the shelter or TNR partner, or a fiscal sponsor. And a letter of interest from the vet school saying they will place students. Get those two letters before the first application, not after.

What we bring to the application

A working pilot (the 90-day colony), a dashboard with real numbers, a data layer no other applicant has, and a jobs story through city programs. Grant reviewers see hundreds of "we need a van" applications. They see very few with proof.

How we start before the van exists

Clinic days first. The Sprinter is the year-one prize, not the prerequisite.

Month 1

Two letters

TNR / shelter partner agreement (they hold the 501(c)(3) and the cats). Vet-school letter of interest for student placements — start with the clinical director.

Month 1–2

Borrowed suite

Run the first clinic days in the partner shelter's surgical suite or a teaching facility on weekends. Supervising DVM on a day rate. Prove the 3-tables-per-DVM model and the throughput.

Month 2–4

Apply with proof

File the van grants with real clinic-day numbers, the pilot dashboard, and both letters attached. Stack 3–4 funders; no single one has to cover $300k.

Month 6–12

The van

Order the build-out (lead times run months). Register the mobile premises with the VMB, DEA registration, insurance. First road day is a city event with the sponsor's name on the side.

For the city

What we're asking for on the clinic side

  • An introduction to the shelter's veterinary lead and surgical-suite schedule
  • A letter of support we can attach to the van grants
  • A supervising-DVM day rate for pilot clinic days, or the name of the fund that covers it
For a vet school or RVT program

We supply a supervised, high-volume, well-documented spay/neuter caseload in California — with a licensed HQHVSN DVM in the room and every case logged. Tell us what your placement rules need and we'll build the clinic day around them.

Rules that don't bend

Direct supervision, always

Students operate only with the licensed DVM physically present in the same room and immediately able to take over. The DVM is the veterinarian of record for every cat.

Three tables, not four

One experienced DVM can safely verify three simultaneous student surgeries. A fourth table in a van is cramped and raises patient risk. We don't do it.

RVTs on anesthesia

The DVM cannot supervise surgery and monitor anesthesia at once. Registered technicians run prep and monitoring on every table, every case.

Licensed premises

The van (or the borrowed suite) is a registered veterinary premises with a DVM-in-charge, controlled-drug logs, and medical-waste handling. No pop-ups.
