Adopting a senior pet: taking home an older dog or cat
Updated By PetymFacts checked against official sources on
Quick answer
An older dog or cat is often calmer, already house-trained and more predictable than a puppy or kitten, and its health issues are usually known. Ask the shelter for every record and medicine, set up non-slip floors and an easy bed, keep the routine steady, and see a vet in the first week with the papers.
Dogs count as senior from about 6 to 11 years depending on size, and cats from over 10. Old age is not a disease, AAHA says, so drinking more, stiffness, weight loss or confusion should go to the vet rather than being put down to age. Senior cats should see a vet at least every 6 months; ask your vet what suits your dog.

Why adopt an older dog or cat?
Fewer surprises. An adult pet's size, character and habits are already there to see.
RSPCA Australia makes the case plainly: older animals tend to be calmer, are already used to family life, have likely had some training, and are more predictable and a safer choice than a puppy or kitten, which change quickly and need many clean-ups while they learn. Any inherent health problems are likely to be known already and may be managed. An adult dog or cat still has plenty of energy for walks and play.
Senior pets often wait longest for a home. ASPCA notes that older animals are typically the last to be adopted, and that age is not what decides how much affection an animal shows a new owner: older pets bond with new families too. Myths that older pets are sick, unfriendly or unsafe around children should not be assumed about any individual animal.
In an Indian home, an older pet can suit people who would struggle with a puppy: a couple in a small flat, someone working from home, or older parents who want a calm companion. It also asks something of you. You may have fewer years together, more vet visits, and a time when you need to make decisions about its comfort. Go in with that understood, and plan for it from the first week.
At what age is a dog or cat a senior?
It depends on size for dogs. Your vet places your own pet, and may call it senior earlier.
| Senior from about | Source | |
|---|---|---|
| Small or toy dog (under about 9 kg), such as a Shih Tzu or Pomeranian AVMA | 8 to 11 years | AVMA |
| Medium dog (about 9 to 23 kg), such as a Beagle or many indies AVMA | 8 to 10 years | AVMA |
| Large dog (about 23 to 41 kg), such as a Labrador or German Shepherd AVMA | 8 to 9 years | AVMA |
| Giant dog (over about 41 kg), such as a Great Dane AVMA | 6 to 7 years | AVMA |
| Cat, senior AAHA/AAFP (Journal of Feline Medicine and Surgery, 2021) | Over 10 years | AAHA/AAFP 2021 |
| Cat, by International Cat Care's stages International Cat Care | Mature from 7, senior 11 to 14, super senior from 15 | International Cat Care |
AVMA gives its dog bands in pounds; Petym converted them to kilograms.
Is an older pet right for your home?
Match the pet's needs to your home, your hours and the people in it.
If You live in a flat with a lift and smooth tiled floors
Fine for most older pets, with rugs on the floors. Ask the shelter how the pet manages stairs in case the lift fails in a power cut. RSPCA
If You are out for long hours
A calm senior cat, or an older dog that copes alone, can suit you, but older dogs may need the toilet more often. Plan a walker or a drop-in visit. Drop-in visits RSPCA
If You have young children
Choose a pet the shelter knows is relaxed with children, and give it a place to retreat. Stiff or sore animals may not enjoy being handled. PDSA
If You already have a pet
Introduce slowly with separate food, water, beds and, for cats, separate trays. Older animals cope less well with change. RSPCA Australia
If The pet has a known condition such as kidney disease or arthritis
Ask the shelter's vet what daily care it needs, and whether you can manage the medicines and visits. Read the medication guide. Senior pets and pets on medication Cornell Feline Health Center
What should you ask before adopting an older pet?
Write the answers down. They become the first page of your pet's care sheet and save your vet time.
- Is the organisation on AWBI's recognised list? Ask for a written adoption agreement. Animal Welfare Board of India
- Every medical record: vaccines, deworming, tick and flea treatment, blood tests, and any diagnosis. International Cat Care
- Every medicine it takes, with the dose written by the vet on the label, and enough to last until your own vet visit. US Food and Drug Administration
- What it eats, how much and when, and any food it must not have. Keep the same food at first. RSPCA
- Its toilet habits: how often an older dog needs to go out, or what litter and tray a cat uses. RSPCA
- How it moves: stairs, jumping, slippery floors, getting into a car. RSPCA
- How it is with children, other dogs, cats, strangers and being handled or groomed. RSPCA
- Whether it is sterilised and microchipped, and the microchip number. PDSA
- Why it came to the shelter, if known, and what it was used to: a flat, a garden, time alone. RSPCA
How do you set up your home for an older pet?
Small changes to floors, beds and bowls make the biggest difference for stiff joints and tired eyes.
Do
- Put rugs or mats on smooth, slippery floors where your dog walks; tiled Indian floors are hard for older dogs. RSPCA
- Give a thick, supportive bed, such as memory foam, in a warm, draught-free spot away from a cold AC blast. PDSA
- For a cat, a litter tray with at least one low side, soft litter, and bowls within easy reach. International Cat Care
- Steps or a ramp to a favourite sofa, bed or window ledge for a cat. International Cat Care
- Fresh water in several bowls in different rooms, especially for an older cat. Cornell Feline Health Center
- Keep a predictable routine. Older dogs prefer it, and older cats do not cope well with changes to routine. International Cat Care
Don’t
- Leave an older dog that needs the toilet often without a way to reach its toilet area. RSPCA
- Give any human painkiller. Many are toxic to pets, and paracetamol can be fatal to cats. International Cat Care
- Plan sudden long treks after quiet days. Steady, gentle daily walks suit sore joints better. PDSA
- Put a stiff cat's food, water or tray where it has to jump. International Cat Care
- Leave an old pet on a balcony or in a closed room without a fan on a hot afternoon. PDSA
What do the first weeks with an older pet look like?
Petym's practical plan for an older dog or cat, built from the RSPCA, International Cat Care and the vet sources on this page.
Day 1, a dog
Let it toilet outside before entering, show it water, bed and the toilet route, then leave it to rest. Expect accidents and never punish. RSPCA
Day 1, a cat
Start in one quiet room with bed, food, water, a tray and a place to hide. Let it come to you. RSPCA Australia
Days 2 to 3, a cat
Open up more of the home over the next few days. Keep it indoors while it learns the new place. RSPCA Australia
Within the first week
First vet visit with every record and medicine. Ask for a weight, body and muscle condition score as a baseline. WSAVA Global Nutrition Committee (chart by Tufts University)
Weeks 1 to 2
Same food, meal times, walks and medicine times as before. Change food only gradually, if your vet advises it. WSAVA
Weeks 2 to 6
Introduce visitors and new places slowly. A rescue may take quite a while to settle; older pets cope less well with change. RSPCA
Every 6 months or as advised
Health checks. AAHA/AAFP advise at least every 6 months for senior cats; ask your vet what suits your dog. AAHA/AAFP (Journal of Feline Medicine and Surgery, 2021)
What happens at an older pet's first vet visit, and does it still need vaccines?
A full check, a review of every record and medicine, and a plan your vet sets for this pet.
Take every paper and every medicine box. The vet will examine the pet, weigh it and score its body and muscle condition: WSAVA notes that an older pet can lose significant muscle even while overweight, and that muscle loss usually shows first along the spine. Ask whether blood and urine tests make sense as a baseline. For cats, Cornell says chronic kidney disease affects up to 40% of cats over 10 and 80% of cats over 15, and creatinine usually rises only after about 75% of kidney function is lost, so early tests can matter.
Older pets still need protecting. WSAVA's core vaccines and rabies apply to dogs of every age in India, and one study found older dogs vaccinated more than three years earlier were less likely to keep protective antibodies, so WSAVA suggests boosting older dogs every three years or perhaps more often. Senior cats need their own plan. Your vet decides what is due from the record and the pet's health, along with deworming and tick and flea control.
Use the visit to plan for comfort, not only for illness. AAHA's 2023 senior care guidelines start from the principle that old age is not a disease, and plan care around the pet, including changes to its surroundings. Ask your vet which changes to watch for and how often to come back.
It also helps to know where your pet sits in its life. AAHA's canine life stage guidelines divide a dog's life into puppy, young adult, mature adult, senior and end of life, and vets plan checks and care by stage. With an older adoptee you may move through the last two stages together, so ask early how your vet judges comfort and quality of life, what pain looks like in this pet, and which signs mean you should come in sooner. Writing those answers into the care sheet means a family member or a sitter can spot the same signs when you are not there.
Which age-related conditions should a new owner know about?
Common in older dogs and cats, and often treatable or manageable. Your vet diagnoses and treats; these are the words you will hear.
- Arthritis (osteoarthritis)
- Wear in the joints that causes stiffness and pain. Keeping a pet slim takes strain off sore joints. Arthritis is very common in older cats and often goes undiagnosed, because cats hide pain. PDSA
- Chronic kidney disease
- Common in older cats. Signs include drinking more and weight loss. Good hydration matters, and a kidney diet set by your vet can help. Cornell Feline Health Center
- Dental disease
- As many as 85% of cats aged three and over are thought to have some dental disease. Bad breath, drooling or eating less can point to a sore mouth. International Cat Care
- Cognitive dysfunction syndrome
- Age-related brain changes in dogs: disorientation, changed sleep, house-soiling and anxiety. Play, interactive toys and exercise help; the vet rules out other causes first. Cornell University College of Veterinary Medicine
- Overgrown claws
- Older cats' claws can overgrow, and this can point to a medical problem such as hyperthyroidism. Trim when needed and mention it to your vet. International Cat Care
- Obesity
- Older dogs are more at risk, and extra weight makes osteoarthritis worse. Measured meals and body condition checks help. RSPCA
What should an older pet eat, and how do you care for it in Indian heat and monsoon?
The RSPCA says many dogs benefit from moving gradually onto a diet made for senior dogs from around seven, with a close eye on weight. WSAVA notes that a food for all life stages is formulated for growth and may be richer than an older pet needs, and advises choosing a complete and balanced food with your vet's help. Any change should be gradual, over at least three to four days. A pet with kidney disease, diabetes or another condition may need a prescription diet that only your vet should start or stop. Keep treats under about 10% of the day's calories, and keep onion, garlic, grapes, chocolate and xylitol away as for any pet.
Older pets handle heat less well. PDSA lists older dogs among those most at risk of heatstroke, and very old cats are less able to regulate their temperature. In summer, keep a cool room with a fan on the inverter, walks only in the early morning and after sunset, and water in several bowls. In the monsoon, dry an older dog's paws and belly after walks, check for ticks, and give it a mat by the door so wet tiles do not become a fall. International Cat Care suggests a litter tray even for cats that usually go outside, and in a north Indian winter a soft thermal blanket and a bed out of draughts help. Brush gently: grooming is a chance to find lumps, and a cat that grooms less may be in pain.

Possible kidney disease or another illness. Book the vet soon and take a note of when it started. Cornell Feline Health Center
If Stiffness, struggling to get up or climb stairs, or a cat that no longer jumps
Talk to your vet: treatments may help. Give only what your vet prescribes. RSPCA
If Seeming lost, pacing at night, or sleep that has flipped
Keep the routine steady and call your vet, who needs to rule out medical causes. Cornell University College of Veterinary Medicine
If Toilet accidents or a change in toilet habits
Discuss it with your vet; incontinence can have a treatable cause. RSPCA
If A new lump, or one that bleeds or grows quickly

If Panting, weakness or collapse in the heat
Cool with water away from the face, make a breeze and call the vet straight away. PDSA
What changes the cost of an older pet, and who looks after it when you travel?
Petym does not quote figures. These are the factors, and the care that suits older pets best.
Older pets prefer a predictable routine, the RSPCA says, and International Cat Care notes older cats do not cope well with changes to theirs. For a trip, a sitter who stays in your home or visits several times a day is usually gentler than boarding. When Petym opens in your city, the sitter follows the plan you write, including every medicine exactly as your vet prescribed, logs it as it happens and sends a daily photo update. Petym's guides to senior pets and medication, and its answers on end-of-life questions, cover the later years.
- Known conditions and daily medicines, and how often your vet wants to see the pet.
- Health checks: at least every 6 months for senior cats, and as your vet advises for dogs.
- Diet: a senior or prescription diet set by your vet.
- Home changes: rugs, a supportive bed, a low-sided litter tray, ramps or steps.
- Dental care, which is common in older cats and dogs.
- Care when you are away: older pets usually do better at home than in a new place.

Questions owners ask
Is it a good idea to adopt an old dog?
- For many homes, yes. RSPCA Australia says older dogs tend to be calmer, are often already house-trained and have had some training, and their health issues are usually known. You may have fewer years together and more vet visits, so check that you can manage the pet's care and any medicines first.
At what age is a cat considered senior?
- The 2021 AAHA/AAFP feline life stage guidelines call a cat senior when it is over 10 years old, and advise a vet visit at least every 6 months from then. International Cat Care uses mature from 7, senior from 11 to 14 and super senior from 15.
Will an older pet bond with me?
- Yes. ASPCA says age is not what decides how much affection an animal shows its new owners. Some older pets take a little longer to settle in a new home, so give it a quiet place, a steady routine and time, and let it come to you.
Does an adopted senior dog need vaccines?
- Usually, yes. Core vaccines and rabies apply to dogs of every age in India, and one study found older dogs vaccinated more than three years earlier were less likely to keep protective antibodies. Your vet decides what is due from the record and the dog's health.
How often should an older pet see the vet?
- For cats over 10, the AAHA/AAFP guidelines say at least every 6 months, more often with a long-term condition. For dogs, ask your vet what suits your senior. Regular checks give your vet a chance to find changes early, before they become a crisis.
How do I help an older cat settle in a new home?
- Start it in one quiet room with its bed, food, water, a tray with a low side and somewhere to hide. Let it come to you, then open up more of the home over a few days. Keep the routine steady: older cats do not cope well with change.
What should I feed a senior dog I have just adopted?
- Keep the food it was eating at first, then ask your vet. The RSPCA says many dogs benefit from a senior diet from around seven, and a pet with a condition may need a prescription diet. Change gradually over several days and keep a close eye on weight.
Can I leave an older adopted pet with a sitter when I travel?
- Yes, and for many older pets a sitter at home suits better than boarding, because the RSPCA and International Cat Care both say older animals prefer a predictable routine. Write down every medicine and what to watch for, and arrange a meet and greet first.
