Cats By The Tracks at PetSmart Milpitas
Cats By The Tracks is a foster-based rescue rather than a shelter with its own building, so our cats live in volunteer foster homes rather than kennels until they’re adopted. We hold adoption hours at PetSmart, 175 Ranch Drive, Milpitas, CA (store hours 9am–7pm), where you can meet our currently adoptable cats in person. This is the same foster-based model we also use at our Bakersfield adoption center, so the experience of meeting a cat is consistent across our locations. See our full adoption centers page for current cats and hours.

Because our cats come from foster homes rather than a kennel environment, they typically arrive already comfortable around people and, in many cases, other household pets — something worth asking about when you meet a specific cat.
Silicon Valley Animal Control Authority
Silicon Valley Animal Control Authority (SVACA), based in nearby Santa Clara, is a municipal shelter option worth checking if you want a lower flat fee than a larger nonprofit shelter typically charges. Adult cats run around $100 and kittens around $150, covering spay/neuter, vaccinations, a health exam, a behavior evaluation, and a microchip. SVACA occasionally runs promotional pricing as well, so it’s worth checking their current listings before you visit.
Why Are Bay Area Adoption Fees Higher Than Other Parts of California?
Adoption fees in Milpitas and the surrounding South Bay tend to run noticeably higher than in the Central Valley — compare HSSV’s $195–$200 range here to the $75–$130 typical in Fresno. The gap mostly reflects the higher cost of veterinary care, staffing, and facility operation in the Bay Area generally, not a difference in what the fee actually covers. Foster-based rescues, which don’t carry the overhead of a large standalone shelter building, are often able to keep fees lower or set them per cat instead.
Large Shelter vs. Foster-Based Rescue: What’s the Real Difference?
| Large Shelter (e.g. HSSV) | Foster-Based Rescue (e.g. Cats By The Tracks) | |
|---|---|---|
| Where cats live before adoption | On-site kennels at a dedicated facility | Volunteer foster homes |
| Visiting hours | Set daily hours at a fixed location | Scheduled hours at a partner pet store |
| Adoption fee | Typically a flat rate, higher due to facility overhead | Often set per cat based on individual medical needs |
| Cat socialization | Varies by length of shelter stay | Cats are already living in a home environment |
What to Ask Before You Adopt
Whichever organization you choose, a few questions up front help avoid surprises once the cat is home:
- Has this cat already been spayed/neutered and fully vaccinated, or is anything still scheduled?
- Is there a trial or return period if the cat doesn’t adjust well?
- What does this cat’s personality look like around other pets, children, or a smaller apartment?
- Is there a waitlist or appointment requirement, or can you visit and meet cats the same day?
- Who do you contact afterward with questions about settling the cat in?
Foster-based rescues like Cats By The Tracks can often answer the behavior and personality questions in more detail, simply because the cat has been living in an actual foster home rather than a shelter kennel.
How to Adopt a Cat in Milpitas, Step by Step
- Decide whether a larger shelter or a foster-based rescue fits what you’re looking for.
- Check current adoption hours — HSSV keeps a walk-in schedule, while Cats By The Tracks holds scheduled hours at PetSmart.
- Submit an application if required before visiting in person.
- Meet the cat and ask about its personality, history, and any medical notes.
- Pay the adoption fee and take home the cat’s medical records.
