Kitten Care Guide
Felis catus
Most of what a new kitten needs — litter training, food, vaccines, socialization — overlaps in the first few months, which is exactly why the early weeks feel so busy for new owners.
Lifespan
13-17 years on average, often longer indoors
Adult size
Typically 3.5-5.5 kg (8-12 lb) as an adult, breed-dependent
Diet
Kitten-formulated food, several small meals a day tapering as they mature
Temperament
Playful and curious; socialization in the first weeks shapes adult friendliness
Housing
Indoor space with a litter box, scratching post, and vertical territory (shelves/trees)
Legal notes
Municipal cat licensing requirements vary by city in Canada — check whether your municipality requires it
Kittens are naturally quick to pick up habits like using a litter box, but the first few months are still a busy stretch of overlapping needs — food transitions, vaccine visits, socialization, and kitten-proofing a home that's suddenly full of things to climb and knock over.
Litter box training
- Most kittens instinctively understand digging and covering behaviour, so litter training is often mostly about placement and access rather than teaching from scratch
- Provide at least one litter box per cat plus one extra, placed in quiet, easily accessible locations
- Use a lower-sided box for very young kittens who may struggle to climb into a standard adult box
- Scoop daily — kittens are more likely to avoid a dirty box than adult cats sometimes tolerate
- If accidents happen outside the box, avoid punishment; instead check for a location, cleanliness, or box-size issue and clean accident spots thoroughly to remove scent
Feeding schedule & food
- Feed a food specifically labelled for kittens (or 'all life stages') rather than adult cat food, since kittens need more calories and protein for growth
- Very young kittens typically need 3-4 small meals a day, tapering to 2-3 meals by around 6 months as they approach adult size
- Introduce any new food gradually over about a week to avoid digestive upset
- Keep fresh water available at all times, separate from the food bowl
- Follow feeding guidelines on the food packaging as a baseline, adjusting for the individual kitten's body condition and your vet's guidance
Vaccination schedule overview
- Kittens typically begin their core vaccine series around 6-8 weeks of age, with boosters roughly every 3-4 weeks until about 16 weeks old
- Core vaccines generally protect against diseases like feline panleukopenia, calicivirus, and herpesvirus; rabies vaccination timing and requirements vary by province
- The exact schedule and additional vaccines recommended (such as for FeLV) depend on the kitten's lifestyle and regional risk factors — confirm the specific plan with your veterinarian rather than following a generic timeline
- Keep vaccination records, since boarding, grooming, and daycare facilities often require proof
- Schedule the first vet visit as soon as possible after bringing a kitten home, even before vaccines are due, for a general health check
Spay/neuter timing
- Spaying or neutering is commonly done around 4-6 months of age in Canada, though some vets and shelters perform it earlier — timing recommendations vary by clinic and the kitten's individual health
- Confirm the recommended timing with your vet, since factors like breed, size, and health history can shift the ideal age
- Spaying/neutering before the first heat cycle in females is often associated with additional health benefits, which is part of why many vets recommend earlier timing
- Recovery is typically quick, but follow your vet's specific aftercare instructions, including any activity restrictions and e-collar use
- Many municipalities and shelters offer lower-cost spay/neuter clinics, which can be worth looking into for cost planning

- Canary
A canary in a cage too small or too quiet often isn't sick — it's under-stimulated; give it flight room and daylight hours and most 'problems' resolve on their own.
- Llama
A lone llama is a stressed llama — they're herd animals first, and no amount of pasture substitutes for the company of at least one other llama or alpaca.
- Cow / Cattle
Cattle need acres, not a backyard — plan on roughly 0.4 to 0.8 hectares of pasture per animal before you plan anything else.
- Alpaca
Alpacas were bred for cold, high-altitude terrain, which makes them one of the better-suited fibre livestock for a Canadian winter — but they still need a herd and a shear once a year, without exception.
