Dogs & cats
Cat (mixed breed)
Japanese domestic cat / mixed breed
Most important: Indoor-only living and spay/neuter greatly extend lifespan
Basics
- Lifespan
- 14–16 years (indoor cats can live close to 20)
- Weight
- 3–5 kg (prone to weight gain after spay/neuter)
- Temperament
- Varies widely by individual, from wary to very affectionate
- Care difficulty
- Low to moderate (hardy, but obesity, kidney disease and dental care need managing)
- Legal status
- Act on Welfare and Management of Animals. Lifelong care, breeding control, microchip registration
- Key point
- Indoor-only living and spay/neuter greatly extend lifespan
Ecology & traits
- Body
- Body length 45–60 cm. Pupils narrow to slits; whiskers gauge width. Short-tailed cats are common in Japan
- Origin & range
- Descended from the African wildcat of the Middle East. Arrived in Japan from the continent around the Nara–Heian period
- Wild habitat
- Ancestors lived in semi-desert and arid regions. Japanese cats live alongside people and adapt well to heat and cold
- Activity & sleep
- Crepuscular: most active at dawn and dusk. Sleeps 14–16 hours a day
- Social behavior & people
- Naturally a solitary hunter. Strongly territorial; in multi-cat homes, separate resources
Characteristic behaviors
- Prefers high places and gets exercise by climbing. A cat tree works well
- Scratching marks territory and maintains claws. Provide several dedicated scratchers
- Instinctively eliminates in sand and avoids a dirty litter box. Clean at least once a day
Common illnesses: warning signs & prevention
Chronic kidney disease
SignsThe most common disease in senior cats. Increased thirst and urination, weight loss, dull coat, vomiting, bad breath. Almost no symptoms early on
PreventionBlood and urine tests 1–2 times a year from age 7. Add water stations and use wet food. Caught early, a therapeutic diet can slow progression
Lower urinary tract disease
SignsFrequent trips to the litter box, passing only a little, bloody urine, urinating outside the box. Urethral obstruction in males becomes dangerous within hours
PreventionOne litter box per cat plus one, always clean. Increase water intake. Avoid obesity and stress. If no urine is passed, see the vet immediately
Obesity / diabetes
SignsRibs cannot be felt, belly sags. Diabetes: increased thirst and urination, weight loss despite eating, walking on the hocks of the hind legs
PreventionAfter spay/neuter, cut food by 10–20%. Treats no more than 10% of total intake. Weigh and record monthly
Periodontal disease / stomatitis
SignsBad breath, drooling, chewing on one side, resenting the mouth being touched, wanting to eat but not eating, red gums
PreventionGet kittens used to tooth brushing; brush 3+ times a week. Annual oral check from age 3. Have tartar removed at the vet
Hyperthyroidism
SignsAge 10+, losing weight despite a good appetite, restlessness, yowling at night, vomiting, diarrhea, rapid heart rate
PreventionIf a senior cat eats well but loses weight, get a blood test. It can be managed with treatment, so early detection is key
Hairballs / constipation
SignsFrequently vomiting hairballs, retching without bringing anything up, small hard stools, straining for a long time in the box
PreventionBrush daily during shedding season. Hairball-control food or cat grass. Increase water intake; if no stool for 3 days, see the vet
Warning-sign checklist
Check once a day. If even one applies, contact an animal hospital early.
First aid for illness
No urine passed, crying in the litter box
Suspect urethral obstruction. Do not press the abdomen; note the time of the last urination and go to the vet the same day, even at night. In males this is life-threatening within hours
Ongoing vomiting or diarrhea
Vomiting 3+ times a day, blood in it, or lethargy: see the vet immediately. Photograph the vomit or stool and offer water in small amounts
No appetite, lethargic
Not eating for 24+ hours risks hepatic lipidosis; see the vet. Do not force-feed; record weight and water intake
Mouth pain, cannot eat
Do not force the mouth open. Offer warmed wet food; if the cat cannot eat, see the vet the same day for an oral exam
Common injuries: prevention & first aid
Fall from a height
PreventionFall-prevention netting on windows and balconies. Locks on screen doors. Do not let your guard down even on high floors
First aidEven if moving, internal organ or pelvic injuries are possible. Wrap in a towel, keep level in a carrier, and see the vet the same day
Cat fight wounds
PreventionDo not let the cat outdoors. In multi-cat homes, watch compatibility, separate hiding spots and bowls, and reduce fights with spay/neuter
First aidBite wounds abscess after a few days. Wash the wound; if swelling, heat or lethargy appear, see the vet the same day and ask about antibiotics
Burns
PreventionKeep away from stoves and heaters. Beware of low-temperature burns from kotatsu tables and heated carpets; allow free entry and exit
First aidCool the area under running water for 10 minutes. Do not apply ice. If the skin is red or fur is falling out, see the vet the same day
Torn or broken claw
PreventionTrim claws every 2–3 weeks. Reduce curtains and carpets where claws can catch
First aidPress with gauze to stop bleeding. If the claw is torn out at the root or the area swells, see the vet the same day to prevent infection
Zoonoses (diseases that can spread to people)
Cat scratch disease
RouteScratches and bites (bacteria carried by fleas)
PreventionYear-round flea prevention. Wash wounds immediately with soap and running water. See a doctor if lymph nodes swell
Pasteurellosis
RouteBites, scratches, mouth-to-mouth feeding
PreventionDo not feed mouth-to-mouth. If a wound swells or fever develops, see a doctor the same day
Toxoplasmosis
RouteOocysts in feces, raw meat
PreventionClean the litter box daily. Pregnant women should wear gloves or avoid handling it. Do not feed raw meat
Roundworm
RouteEggs in feces reach the mouth via hands or sandboxes
PreventionDeworm kittens. Wash hands after cleaning the litter box. Annual fecal exam
Husbandry: food, water, toys, nest, bedding
Food
- Complete and balanced food 2–3 times a day; start slightly below the package amount and adjust
- After spay/neuter, switch to a dedicated food or cut the amount by 10–20%
- Senior food from age 7; therapeutic diet if kidney disease is present
Water
- Several water stations in quiet spots. Change daily
- Increase intake with wet food or a water fountain
Never feed
- Onions and alliums, chocolate, grapes, alcohol
- Lilies (pollen and vase water also cause kidney failure)
- Human food, large amounts of dried sardines or sashimi (urinary stones, vitamin deficiency)
Toys & play
- Wand toy twice a day, 10–15 minutes of hunting play
- Place several scratchers to draw attention away from walls and furniture
- Put away string, rubber bands and plastic after play
Nest, bed & hideout
- Provide high spots and a box to hide in as an escape
- For senior cats, a warm bed with few steps
Bedding & litter
- One litter box per cat plus one, at least 1.5 times the cat's body length
- Do not switch litter suddenly; mix in gradually
- Remove waste daily; wash the whole box monthly
Housing: cage, exercise, temperature & humidity
Cage / housing material
Steel 2–3 tier cage. Free-roaming is the norm; use for visitors or recovery
Size & space
At least 90 cm wide x 60 cm deep x 120 cm high
Layout
- Litter box on the bottom tier, bowls in the middle, bed on top
- Place water away from food bowls and the litter box
- Double-lock the door to prevent escape
Placement notes
- Away from direct sunlight and direct air-conditioner drafts
- Against a quiet wall where the cat can see the family
Exercise, free-roam & walks
- Indoor-only. Prevents traffic accidents, infections and fights
- Provide a cat tree for vertical exercise
- Toy play twice a day to prevent obesity and stress
Temperature & humidity
Temperature20–28°C. Senior cats feel the cold, so keep them warm in winter
Humidity40–60%. Dehumidify in the rainy season to prevent mold and skin disease
Summer & winter
- Summer: run the air conditioner continuously at 28°C or below, water in several places
- Winter: watch for low-temperature burns from heaters and for dryness
Grooming & protection from predators
Nail trimming
Every 2–3 weeks. Cut 2 mm before the quick. If the cat resists, do one claw at a time over several days
Brushing, skin & coat care
Shorthairs 2–3 times a week, daily during shedding season (spring and fall). Reduces shed fur and hairballs
Other care
Brush teeth 3+ times a week. Wipe ears if dirty. From age 7, checkups with blood and urine tests 1–2 times a year
Protection from predators
- Escape-prevention netting on windows and balconies, locks on screen doors
- Separate from dogs and other pets with a gate until they are used to each other
- Heartworm is spread by mosquitoes; discuss preventive medication with your vet
Care precautions (accident prevention)
Foreign-body ingestion
Easily swallows string, rubber bands, hair ties and small toy pieces. If vomiting or not eating, do not induce vomiting; see the vet. Never pull string protruding from the mouth or anus
Being stepped on
Cats weave around your feet, so check where the cat is before walking. If the cat limps or resents touch after being stepped on, see the vet the same day
Getting pinched
Tails and paws easily get caught in doors and sliding doors. Use door stoppers. If the tail hangs limp or the cat cannot urinate, see the vet immediately
Falls
Falls from windows and balconies are the most common accident. Screen locks and fall-prevention netting. After a fall, even a lively cat may have internal injuries; see the vet the same day
Escape
Double door at the entrance. Fit a microchip and ID tag. If the cat escapes, search quietly within 50 m of the house at night and place used litter by the front door
How to safely release a bite
Never do this
- Pulling your hand out (tears the wound deeper)
- Shouting or hitting (the cat gets more worked up and keeps biting)
Safe release procedure
- Stop moving and push the bitten hand gently toward the cat
- With your other hand, drop a towel or blanket over the cat's head
- The moment the cat loosens its grip, withdraw your hand
- Move the cat to another room and leave it alone for 30+ minutes
After the release
Wash the wound under running water for 5+ minutes and disinfect. If swelling, heat or pain develops, see a doctor the same day
Emergency care manual
Go to an emergency vet now (life-threatening)
- No urine passed (especially males)
- Open-mouth breathing, purple tongue
- Seizure, unconscious, fall from a height
- Limp and cold to the touch
See a vet the same day
- Not eating for 24+ hours
- Vomiting 3+ times a day, or bloody urine or stool
- Limping, or reacting fiercely to touch
What to tell the vet & what to bring
Age, spay/neuter status, medical history, when it started and what happened, photos of vomit or urine, vaccination history
Checking consciousness, breathing & heartbeat
- Call the name and poke the body. No response means unconscious
- Watch the chest. Normal breathing is 20–30 breaths per minute
- Feel for a pulse on the inner thigh of a hind leg. Normal is 120–180 per minute
Resuscitation steps
- Lay on a hard surface on the right side, neck extended
- Squeeze the chest just behind the elbows with one hand, 2 compressions per second
- After 30 compressions, close the mouth and blow 2 breaths into the nose
- Check the pulse every 2 minutes and continue until you reach the vet
Stopping bleeding
- Press firmly with clean gauze for 5+ minutes
- For a bleeding paw, wrap a bandage over the gauze for pressure
- For a bleeding claw, press on potato starch or styptic powder
Transport
- Line the carrier with a towel, keep it dark and warm
- If breathing is labored, transport in the sternal (chest-down) position
