Which robotic pet is lightest to hold?

Of the three robotic pets this site lists, MetaCat is the lightest on published listings, at 1.5 kg and 43 by 16 by 20 cm. The Joy for All companion cat and pup are a little heavier, at 3.9 pounds on the manufacturer's site and about 1.9 kg on Australian retailer listings. Weigh the pet against how the person will use it: resting it on a lap needs far less strength than lifting it.

Will a voice-responsive pet work if speech changes?

Retailer and manufacturer listings do not say how well the voice features work with quiet or unclear speech, so do not choose a model for its voice features alone. The companion pup and MetaCat respond to touch as well as voice, and the companion cat responds to petting and movement without any voice commands. A speech pathologist can advise on what is realistic for the person.

Can my plan be changed if my needs change quickly?

Yes. You can ask for a plan variation at any time, and the NDIS says it will tell you its decision within 21 days of having the information and evidence it needs. For bigger, ongoing changes a plan reassessment creates a new plan. The NDIS also says renting assistive technology may be the better option when needs are changing quickly.

What if I was diagnosed with MND after 65?

It depends on when you became an NDIS participant. The NDIS age requirement is about your age when the access request was made, not when you were diagnosed. If you joined before 65 you can stay on the NDIS after 65, subject to the rules about permanent aged care. If you were not a participant before 65, a new access request will not meet the age requirement, so look to aged care instead, starting with an assessment through My Aged Care.

Where can I get advice specific to my condition?

MS Australia publishes national information about multiple sclerosis. For MND, MND Australia says the state MND associations provide support for people living with MND, their families and their carers, and in Victoria that is MND Victoria. For Huntington's disease, ask the treating neurologist or GP which local service to contact. An OT who knows the person is the best adviser on choosing a robotic pet.

Robotic pets for MS, MND and Huntington's disease

For someone living with multiple sclerosis (MS), motor neurone disease (MND) or Huntington’s disease, the right robotic pet is one they can keep using as their abilities change: light enough to rest on a lap without being lifted, woken by a gentle stroke, and able to be quietened. NDIS participants can buy one as low-cost assistive technology when it links to their disability and a plan goal. A person who first applies after turning 65 cannot join the NDIS, so aged care becomes the route.

Why progressive conditions change the choice

MS Australia’s 2025 prevalence report, produced with the Menzies Institute for Medical Research, counts 37,756 Australians living with MS, a 13.3% increase in the three years since 2021. MND Australia says it supports 2,688 Australians currently living with MND. We could not confirm a current national figure for Huntington’s disease, so we have left one out.

What these conditions share is change over time. A pet chosen for how a person holds, moves and talks today may be harder to use later. That shapes three decisions:

Pick for next year as well as now. If grip or arm strength may change, choose a pet that works without lifting or squeezing.
Consider a trial before buying. The NDIS page on renting assistive technology says renting may be better when your needs are changing quickly or you want to trial an item for an extended period. Our page on hiring or trialling a robotic pet with NDIS funds covers the options.
Plan who keeps it running. Changing batteries or plugging in a charger may become a carer’s job.

The research is thin. A PubMed search we ran in October 2026 found no trials of robotic companion pets with people living with MS, MND or Huntington’s disease. The nearest was a 2026 Italian study in which 20 people with MS completed tasks with Pepper, a humanoid robot, and rated it as highly usable. That study did not test a pet. Most robotic pet evidence comes from dementia care.

Weight, grip and touch sensors

The manufacturer of the Joy for All companion cat and pup, Ageless Innovation, lists each at 3.9 pounds, a little under 1.8 kg. Australian specialist retailers list them at about 1.9 kg. MetaCat is listed at 1.5 kg by an Australian retailer. For someone with weak arms or grip, plan for the pet to rest on a lap, cushion or bed rather than be held up.

Companion cat: listed weight: About 1.8 to 1.9 kg; what wakes it or gets a response: Responds to petting and motion; a gentle pat on the back wakes it after it sleeps; sound control: Mute function on retailer listings; power: 4 C cell batteries.
Companion pup: listed weight: About 1.8 to 1.9 kg; what wakes it or gets a response: Responds to touch and voice; you can feel its heartbeat; sound control: Mute keeps the heartbeat-like vibration and small movements; power: 4 C cell batteries.
MetaCat: listed weight: 1.5 kg; what wakes it or gets a response: Touch sensors on the head, chin and back; voice commands; sound control: Silent mode; power: Rechargeable, USB-C cable.

MetaCat sells for $349 to $399, the pup for $269 to $315 and the cat for $259 to $300 at Australian specialist retailers, which keeps all three under the $1,500 limit for low-cost assistive technology. Our page on companion cats and pups for NDIS participants has more on each product.

For a person who uses a wheelchair, ask the OT where the pet will sit, such as on a lap tray or a cushion, so it stays put without being held.

Speech changes and voice-responsive pets

The companion pup’s BarkBack feature responds to voices and conversation, and MetaCat accepts voice commands. Both also respond to touch. If the person’s speech is changing, a pet that responds mainly to touch and movement, like the companion cat, does not depend on being understood.

A speech pathologist who knows the person can advise whether voice features are realistic now and are likely to stay that way. If they are not, treat voice features as a bonus rather than the reason for choosing a model.

Fatigue, mood and cognitive changes

A robotic pet should cost the person no energy they would rather spend elsewhere. Retailer listings say the companion cat goes to sleep if it is not touched for a few minutes, and MetaCat switches to sleep mode when petting stops. Neither needs feeding, walking or vet visits.

We have not found research showing that robotic pets improve mood or fatigue in MS, MND or Huntington’s disease, so do not buy one expecting a treatment effect. If the person also has memory or thinking changes, the dementia research summarised on our page about robotic pets for younger people with dementia is the closest guide. Our page on robotic pets after an acquired brain injury covers similar practical questions about one-sided weakness, noise and routine.

Ten checks before you buy

Holding. Will the pet rest on the person’s lap, a tray or the bed, so nobody has to hold its full weight?
Waking. Can the person wake it with the movement they have now, such as a stroke along the back?
Next year. If hand or arm use declines, will the pet still respond to lighter or less precise contact?
Voice. Is the person’s speech likely to stay clear enough for voice features to matter?
Sound. Does the household want barking, purring or meowing, or would the mute or silent setting suit better?
Power. Who will change the 4 C cell batteries or connect the USB-C charger, and how will they know when it is due?
Switch. Where is the on and off switch, and does the person or a carer operate it?
Cleaning. Who will brush or wipe the fur, and how often?
Evidence. Is there a plan goal the pet supports and a short note from the OT or another therapist?
Review. When will you check whether it is still being used, for example after a month and again at the next check-in?

When needs change: plan variations and reassessments

When needs change, the NDIS offers two routes. A plan variation changes part of the plan, such as goals or the way funding is managed, without creating a whole new plan. You, your plan nominee or child representative can ask for one at any time, and someone else, such as a support coordinator, can ask with your consent. The NDIS says it will tell you its decision within 21 days once it has the information and evidence.

A plan reassessment creates a new plan, and the NDIS says it may happen when there are significant and ongoing changes to your support needs. For short-term changes, the NDIS says you can use your flexible budgets in the way that best suits your needs. A decision not to vary or not to reassess a plan can be reviewed if you ask within 3 months.

Diagnosed after 65: aged care instead of the NDIS

The National Disability Insurance Scheme Act 2013 sets an age requirement in section 22: a person must have been aged under 65 when their access request was made. A person who is diagnosed and first applies after their 65th birthday will not meet that test, and they will need to look to the aged care system instead, which starts with My Aged Care.

People who became participants before 65 are in a different position, and the NDIS has rules about when they leave. Our comparison of staying on the NDIS or moving to aged care at 65 sets out those rules and how aged care programs treat robotic pets.

Next step

Talk to the person’s OT about weight, positioning and which response suits them now and in a year’s time. When you know what you need, request a quote for a light, touch-responsive robotic pet and include the plan management type. We pass the enquiry to an independent Australian supplier, who quotes you directly.
