Where to Adopt a Cat in London, Ontario

Humane Society London & Middlesex is the fastest route, with kittens at $300, adults at $250 and seniors at $200, fully vetted. The volunteer foster rescues take longer and tell you far more about the cat. London has both kinds, plus a city-run program for the feral cats nobody is adopting. Here is how each one works and which suits you.

The short answer

For speed and selection, go to Humane Society London & Middlesex at 1414 Dundas Street. Kittens are $300, adults $250, seniors $200, and the surgery, vaccines and microchip are already done. For an honest picture of how a cat behaves in a real house, go foster-based: Purrfect Haven, Hollys Hope, Salt Rescue, ARF Ontario or Animalert. Enquire at more than one, because these groups do not share a waiting list. London licences cats annually, so budget for that too.

London is a good place to adopt a cat, mostly because it has more than one kind of rescue. Some cities have a single shelter and that is the whole story. Here you can book an appointment at the region's open-admission shelter on Dundas Street, or you can talk to a volunteer who has been fostering the same cat in a Wortley Village spare bedroom since March and knows exactly what it does when the smoke alarm chirps.

Those are different experiences and they suit different people. The shelter route is fast and the selection is broad. The foster route is slower and hands you better information. Neither one is a compromise.

London also has a genuine seasonal rhythm that shapes what is available. Kitten season runs spring through autumn. Student turnover at Western University and Fanshawe College adds a second wave of surrenders around lease-end in spring. Adult cats are available year-round and are usually the easier match.

Below is each London organisation, what it charges, and the honest trade-off. If you would rather skip ahead and see which cats are actually available across all of them, the live London cat listings are refreshed regularly.

HSLM and Purrfect Haven fees verified July 2026 from each organisation's own website. The other volunteer groups price per cat rather than by a published tier, so ask about the specific animal when you enquire.

Humane Society London & Middlesex: the fastest route

Humane Society London & Middlesex sits at 1414 Dundas Street and has been operating since 1899. Phone 519-451-0630. It shelters around 2,500 animals a year and it is open-admission, which means it takes in strays, owner surrenders and transfers rather than turning animals away. That is why its cat inventory turns over faster than anywhere else in the city.

Cat fees are published and tiered by age: $300 for a kitten, $250 for an adult, $200 for a senior aged ten or older. Each includes a $50 non-refundable administration fee. The fee covers the spay or neuter depending on age, a microchip, flea treatment with Revolution, initial vaccinations, initial deworming, a rabies vaccination depending on age, and a seven-day supply of food.

Adoptions run by appointment with an adoption counsellor, so phone ahead rather than turning up expecting to leave with a cat the same hour. Bring a carrier. The trade-off with any shelter is that a kennel tells you less about a cat than a living room does. A cat that seems flat and withdrawn behind glass is often a completely different animal a month into a quiet home. Ask staff what they have actually observed, and read our first week guide so the hiding phase does not alarm you.

Purrfect Haven and Hollys Hope: cats only, in foster homes

Purrfect Haven Cat Rescue is a fully volunteer, foster-based rescue working across London. Its adoption fee is $350, covering the spay or neuter, a first set of vaccines, a vet check, flea prevention, deworming and the rabies vaccine. Reach them at 226-578-0115, calls only rather than texts, Monday through Saturday.

Hollys Hope is a small London nonprofit that has placed more than 1,200 cats and kittens. Cats are spayed or neutered, socialised, vaccinated, dewormed, flea treated and tested for FIV and feline leukemia before adoption. It does not accept owner surrenders, so it is not the place to call if you need to rehome your own cat. Adoption starts with an online application followed by a meet and greet.

Both are worth contacting together rather than choosing between. Neither has a large standing inventory at any one moment, and the cat that suits your household may be at either one. Reply times run on volunteer hours, so a two-day gap is normal rather than a brush-off.

Salt Rescue, ARF Ontario and Animalert

Salt Rescue is a London nonprofit running on entirely volunteer effort, rescuing and rehoming both cats and dogs across the London area. It holds adoption hours at London PetSmart locations, which makes it one of the easier groups to meet cats through in person without booking anything. It has also been recruiting foster homes urgently for expecting mothers and kittens.

ARF Ontario, the Animal Rescue Foundation of Ontario, is London-based and foster-based, working with rural and First Nations communities to rescue, rehabilitate and rehome stray cats and dogs. Its process is deliberately thorough: an online application, a reply within 48 hours to schedule a telephone interview with all the adults in your home, a 48-hour foster review, and then an in-person meeting. Expect many days rather than a same-week adoption.

Animalert is a registered London charity that has been placing cats and dogs since 1977, with a foster program where volunteers provide the home and the charity covers the veterinary care. Phone 519-642-7732. Fees are not published as a schedule, so ask about the specific cat.

How to choose, honestly

You want a cat this month. Book with HSLM. Largest turnover in the region, published fees, and the vetting is finished before pickup.

You have a toddler, a dog or a resident cat. Go foster-based. You need somebody who has watched the cat around exactly that, and a kennel cannot tell you.

Your budget is tight. Adopt a senior at $200 rather than a kitten at $300, and read our spay and neuter guide for the City subsidy programs. An adopted cat is already fixed, which is the single largest first-year cost avoided.

You want a kitten specifically. Late spring through early autumn. Ask Salt Rescue and Purrfect Haven as well as HSLM, since foster kittens often go straight from volunteer homes to adopters without ever hitting a shelter listing.

You want to meet cats in person without an appointment. Watch for Salt Rescue adoption hours at London PetSmart locations.

You have found a cat outside. Get it scanned for a microchip before assuming it is a stray. London cats carry identification tags, so a found cat is often traceable.

The free-kitten trap

Classified listings around London fill with free kittens every summer, and they spike again when student leases end. A free kitten is not free. It arrives unfixed, unvaccinated, untested for feline leukemia and unchipped, and you pay for all of it afterwards at full clinic rates plus Ontario's 13% HST on everything that is not the surgery itself.

A $250 HSLM adult cat has several hundred dollars of veterinary work already inside the fee, plus a week of food. Classified sites also carry a genuine scam risk, including deposits taken for animals that never existed. If you want the numbers side by side, our London cat cost breakdown runs the full comparison.

Frequently Asked Questions

Where is the best place to adopt a cat in London, Ontario?

Start at Humane Society London & Middlesex on Dundas Street if you want a cat soon. It is the region's open-admission shelter, it shelters roughly 2,500 animals a year, and cat fees are published: $300 for a kitten, $250 for an adult, $200 for a senior aged ten or older. If you would rather know exactly how a cat behaves at 6 a.m. or around a toddler, go foster-based instead. Purrfect Haven, Hollys Hope, Salt Rescue, ARF Ontario and Animalert all keep cats in volunteer homes across London, so somebody has genuinely lived with the animal you are asking about. Neither route is better. They answer different questions.

How much does it cost to adopt a cat in London?

HSLM publishes a clear tier: $300 for a kitten, $250 for an adult cat, $200 for a senior, each including a $50 non-refundable administration fee. Purrfect Haven charges $350 for a cat. The other volunteer groups set fees per cat rather than by a published tier, so ask when you enquire about a specific animal. Expect those to land in a similar range, because they are recovering the same veterinary work. Anything dramatically cheaper usually means the surgery or the vaccines have not happened yet, and that bill lands on you later at full clinic rates plus 13% HST on the non-surgical parts.

What does the HSLM cat adoption fee include?

The expensive veterinary work, done before pickup. An HSLM cat goes home spayed or neutered depending on age, microchipped, treated with Revolution for fleas, with initial vaccinations, an initial deworming, a rabies vaccination depending on age, and a seven-day supply of food. That bundle costs several hundred dollars ordered separately at a London clinic. Adoption is by appointment with an adoption counsellor rather than a walk-up-and-buy transaction, so phone ahead at 519-451-0630 rather than turning up expecting to leave with a cat that hour.

Does London, Ontario require a licence for cats?

Yes, and this surprises people who have owned cats in other provinces. London runs a Cat Identification program alongside dog licensing, administered by the London Animal Care Centre, and it renews every year with licences expiring December 31. For a cat registered between January 1 and July 1, the fee is $23 if the cat is spayed or neutered and microchipped, $28 if spayed or neutered only, and $53 if the cat is intact. Owners aged 65 and over get $5 off per cat. Registering your new cat is part of the first-week checklist here, not an optional extra.

What is a foster-based cat rescue, and why does it matter in London?

It means the cat lives in a volunteer spare room instead of a shelter kennel until adoption. Purrfect Haven, Hollys Hope, Salt Rescue and ARF Ontario all work this way across the London area. The payoff is information you cannot get anywhere else. Somebody has watched that cat around a vacuum, a resident dog, a thunderstorm on a humid August night, and a five-year-old. A shelter room tells you far less, because most cats behave strangely in one and then turn into different animals three weeks into a quiet house in Byron or Old East Village.

How long does a London cat adoption take?

HSLM moves fastest, though it works by appointment with an adoption counsellor rather than same-hour walk-outs, so book the meeting and expect days rather than weeks. Foster-based groups run slower because they are volunteers with day jobs. ARF Ontario is upfront that its process runs four steps and may take many days, including a telephone interview with all the adults in your household before the foster family reviews it. That slowness is not disorganisation. It is the same care that produces the behaviour notes people want from a foster placement in the first place.

Can I adopt a cat in London if I rent?

Yes, and London rescues expect it in a city where a large share of housing is rented and student turnover is constant. Have written landlord permission or the relevant lease clause ready before you apply, because chasing a landlord for confirmation is the most common reason an otherwise simple adoption stalls for a week. Renting does not disqualify anyone. Being unable to show the cat is allowed does. If your lease is silent on pets, get something in writing rather than relying on a verbal yes, since that protects you as much as it protects the rescue.

Should I adopt a kitten or an adult cat?

An adult is the better bet for most London households, and the HSLM fee gap barely reflects how different the workload is. A kitten at $300 costs $50 more than an adult and brings roughly two years of chaos, night sprinting and furniture testing. An adult arrives with a settled litter habit, a known personality and no interest in climbing your curtains. A senior at $200 is the quietest option of all. If you work full days or live in a smaller apartment near Western University or downtown, an adult or senior cat is usually happier and so are you.

Do London rescues adopt out bonded pairs?

Regularly, and it is worth taking seriously rather than avoiding. Cats who arrived together or bonded in a foster home often settle far faster placed as a pair, so rescues list them that way on purpose. Two cats double the food and the litter but barely change the gear, since they share the tree, the scratching post and eventually your bed. Two settled adults also entertain each other, which matters more than people expect during a London January when nobody is opening a window and the snow off Lake Huron has been falling for three days.

What if the cat I want is already spoken for?

You wait or you look at another cat, and it is not personal. Most rescues process one application per animal at a time, so a cat on hold is genuinely off the market until that falls through. The useful move is staying flexible about which cat rather than which rescue. Cats cycle through London organisations steadily, and the one that suits your household may be sitting in a Purrfect Haven foster home you have not contacted yet, or waiting at a Salt Rescue adoption event at a London PetSmart this weekend.

What should I do if I find a stray cat in London?

Treat it as a different situation than adopting, because it probably is. Many apparent strays are owned cats that slipped out, so check for a collar and tag, get the cat scanned for a microchip at a London clinic, and post locally before assuming it is homeless. London's cat identification tag exists precisely so a found cat can be traced. If the cat is genuinely feral and part of an outdoor colony rather than a lost pet, the City of London runs a free trap-neuter-return program for feral cats inside city limits. Do not bring an unknown cat straight into a home with resident pets.

Why are there so many kittens in London every summer?

Kitten season. Unspayed cats cycle from spring into autumn, so litters land on rescues in waves rather than a steady trickle, and every unfixed cat outdoors compounds it the following year. London adds a second pressure most cities do not have: Western University and Fanshawe College empty out every spring, and some cats get left behind when leases end. If you are looking for a kitten specifically, late spring through early autumn is when London rescues are fullest. If you are open to an adult, you can adopt any month and you will have better information about the cat.
