Robotic pets for people living with acquired brain injury
Choosing a robotic pet for an NDIS participant after a brain injury, with 10 checks on fatigue, memory, noise, one-handed use and therapy goals.
A robotic pet can be worth trying for an adult living with an acquired brain injury (ABI) who would like something to hold and look after at home but cannot manage a live animal. The published evidence is thin: we found one small hospital trial in stroke rehabilitation and nothing on traumatic brain injury, so the choice rests on the person, their therapist and a trial at home. For an NDIS participant the pet is bought as low-cost assistive technology, which means it has to link to the disability and to a goal in the plan.
Why families and therapists ask about robotic pets after a brain injury
Brain Injury Australia, citing the Australian Bureau of Statistics, says over 700,000 Australians have a brain injury with daily activity limitations and participation restrictions. Three in every four of them are aged 65 or under, and as many as two in three acquired the injury before the age of 25. Brain injury is largely a disability of younger and working-age people, which is the group the NDIS covers: a person must be under 65 when they ask to join.
The Victorian Government’s Better Health Channel says it is common for people with an ABI to have increased mental and physical fatigue and some slowing in how fast they process information, plan and solve problems. People may also have changes in behaviour and personality, in physical and sensory abilities, or in thinking and learning. Each of those affects which pet, if any, will suit.
A live animal can be hard to manage after a brain injury. Feeding, walks and vet visits take planning and energy, and a real animal does not stop when the person has had enough. A robotic pet asks for less and can be switched off. It does not replace therapy, company or support workers.
What the research covers
The closest study we found is a randomised trial by Karner and colleagues, published in Clinical Rehabilitation in 2019. It ran in a German neurological rehabilitation hospital with 39 people over 60 who had had a first stroke in the previous three months and were not attending to their left side (left hemineglect). One group spent time with the PARO robotic seal three times a week for two weeks; the other group was read to aloud. The PARO group improved more on tests of neglect, and the robot was well accepted.
That study has clear limits for a family choosing a pet for home:
- It took place in hospital rehabilitation, not at home.
- Everyone was over 60, and the cause was stroke rather than a traumatic injury.
- It used PARO, a therapy robot listed from $6,500, not a companion cat or pup.
- The intervention lasted two weeks, with a further two weeks of follow-up.
Our PubMed searches in October 2026 found no trials of robotic pets after traumatic brain injury, and none testing the companion cats and pups sold in Australia with any brain injury group. Most robotic pet research comes from dementia care and is summarised on our page of robotic pet options for OTs and therapists.
Ten checks for a person with a brain injury
Weights and features below come from Australian retailer product listings we read in October 2026. Confirm them with the supplier before you order.
- Fatigue. The companion cat and pup go to sleep after a few minutes without touch, and MetaCat has on, off and silent modes. A pet that settles by itself makes no demands on a tired person.
- Noise and sensory load. The companion pup has a mute function that keeps a heartbeat-like vibration and small movements without sound. Test the volume in a quiet room first.
- Memory and charging. The companion cat runs on 4 C cell batteries, which are not included. MetaCat has a rechargeable battery and a USB-C cable. Decide who will notice when power runs low and add it to the daily routine or a support worker’s checklist.
- Weakness on one side. Listings give about 1.9 kg for the companion cat and pup and 1.5 kg for MetaCat. A pet that rests on a lap or an armrest does not need lifting, so ask the OT to check where it will sit.
- Switches. Find out where the on and off switch is and whether the person can reach and work it with their stronger hand.
- Frustration. Plan what happens if the pet is pushed away or dropped, and ask the supplier what the warranty covers.
- Voice commands. MetaCat responds to voice commands. See the questions below if the person’s speech has changed.
- Attention to one side. If the person tends to miss things on one side, ask the OT or neuropsychologist where the pet should be placed.
- Cleaning. Agree who will brush or wipe the fur and how often.
- Goal and review. Write down the plan goal the pet supports and set a review date, such as four weeks after it arrives.
The companion cat is listed at $259 to $300, the pup at $269 to $315 and MetaCat at $349 to $399, all under the $1,500 low-cost AT limit. Our page on companion cats and pups compares the three in more detail.
Hospital rehabilitation or the NDIS: who pays for what?
The NDIS supports lists class time-limited, recovery-oriented services and therapies given after a recent medical or surgical event, aimed at improving the person’s function, as health supports. Post-acute rehabilitation is named in that row, so it is generally not an NDIS support. Ongoing supports for a lasting disability are the NDIS’s part.
| Situation | Where the robotic pet question sits | What to do |
|---|---|---|
| In hospital or inpatient rehabilitation after the injury | The health system | Ask the rehabilitation team whether they use robotic pets on the ward |
| At home, an NDIS participant with ongoing needs from the injury | The NDIS, as low-cost AT if the conditions are met | Link the pet to a plan goal and get a therapist’s note |
| At home, not yet an NDIS participant | Neither, until an access request is decided | Apply to the NDIS if under 65, then raise the pet at planning |
| Injured at 65 or over | Aged care rather than the NDIS | Support at Home does not list robotic pets, so plan to pay privately |
Working with the neuropsychologist, OT or behaviour support practitioner
- Occupational therapist: weight, grip, positioning, switch access and the written recommendation. Our goal link and OT recommendation checklist lists 10 points the note should cover.
- Neuropsychologist: memory, routine and how the person understands the pet, including whether they know it is a robot.
- Behaviour support practitioner: if the pet is meant to help with distress or behaviours of concern, it may belong in a behaviour support plan. See robotic pets in NDIS behaviour support plans.
- Speech pathologist: whether voice commands are realistic for the person.
People with progressive neurological conditions face several of the same checks. Our page on robotic pets for MS, MND and Huntington’s disease covers them.
Getting a quote
Before you enquire, note the person’s main needs: fatigue, noise sensitivity, weakness on one side, and who will look after batteries or charging. Then request a quote for a robotic pet suited to someone with a brain injury, with the plan management type included, and we will pass it to an Australian supplier who quotes you directly.
Frequently asked questions
- Can a robotic pet help with fatigue or irritability?
No study we found measured fatigue or irritability after a brain injury, so nobody can promise either will improve. What a robotic pet offers is something calm to hold that goes quiet when left alone. Sound and movement can also be tiring, so try the pet at home and keep short notes on how the person responds on good and bad days.
- Will the hospital rehabilitation team pay for a robotic pet?
That is up to the hospital or health service. Under the NDIS supports lists, post-acute rehabilitation after a recent medical event is a health system support rather than an NDIS one. Ask the team whether they have a robotic pet the person can try on the ward. A pet for home after discharge is a separate question for the NDIS plan.
- Does the NDIS have special rules for robotic pets after a brain injury?
No. The same low-cost assistive technology conditions apply to every participant: the item must relate to the disability, help with a plan goal, be within NDIS rules, be safe and be backed by evidence such as an allied health recommendation. A brain injury changes the evidence you give, for example why fatigue or one-sided weakness led to a particular model.
- Can someone whose speech has changed use a pet with voice commands?
Possibly, but voice control can be frustrating if words come out differently from day to day. Retailers describe the companion cat and pup as responding to petting and movement, with no spoken commands needed, which makes them simpler. A speech pathologist who knows the person can say whether voice commands are worth trying.
- Where can families get brain injury information and advocacy?
Brain Injury Australia describes itself as the central clearinghouse of information and gateway to nationwide referral for Australians living with brain injury. In Victoria, the Better Health Channel lists BrainLink and Brain Injury Matters as sources of help. For an NDIS dispute, the Disability Advocacy Finder on Ask Izzy searches advocacy services by postcode or suburb, and the NDIS Appeals Program funds free advocates for Tribunal reviews.
