The Cat Standard.
Scratchers, caves, trees and toys designed by emergency vet Dr Duncan Houston around what cats actually do: scratch, climb, hunt, hide and sleep. Every piece is tested by Gary, a Ragdoll with opinions.
Cats are not small dogs. The gear should not be either.

Six things owners email us about, what the cat means by it, and where to start. Health changes are a vet visit first; the rest is environment.

Scratching is normal, not naughty. Cats scratch where they already scratch, so put a better surface right there: rope for the upward stretchers, felt or cardboard for the sideways ones.
Shop scratchers
An indoor cat still needs the stalk, chase, catch, kill sequence. Toys that roll, rattle and hide food give it back, five minutes at a time, and a wand session finishes it properly.
Shop toys
Hiding is how cats cope. A covered cave with one entrance beats under the bed, and it means you know where she is. Put it somewhere quiet and leave it alone.
Shop caves
Height is safety to a cat. Give it back on purpose: a tower or perch above the room, near a window, and the top of the fridge loses its appeal.
Shop trees and towers
Solo-play toys work without a human on the other end. Rotate two so neither goes stale, and hide a few kibbles in one so lunch takes effort.
Shop solo-play toys
Most tray problems are location, cleanliness or a litter the cat did not choose. Change one thing at a time. A sudden change in toileting is a vet visit, not a shopping trip.

Four things cats keep choosing, according to the humans who wrote the reviews.
Somewhere to disappear when the doorbell goes. One entrance, soft walls, and a cat who knows exactly where she is.
60 cm of dense paper rope on a weighted 30 by 30 cm base, so the stretch goes up and the post stays put.
Paw holes and a rolling bell ball, so the hunt goes on while you are at work.
A felt play box with feather springs and paw holes, for the cat who needs a job.

Real cats, real homes
Every rating on this page belongs to the product it sits under.
My maine coon finally has a ball he can grab and bunny-kick without it skittering away instantly. The beige colourway blends beautifully into our timber floors.
My persian normally ignores solo toys entirely, but the unpredictable rolling combined with the jingle gets her batting around the room every evening.
BEFORE YOU BUY
Footprint and height are the biggest reasons cat furniture goes back in the box. Two minutes with these tools saves a return—and a disappointed cat.
Sizing tool
Enter your cat's measurements and the floor space you have, and see which bed, cave and tower sizes actually fit.
Health check
Check body condition before choosing a bed size or a feeding routine. A guide for product choice, not a diagnosis.
Ask the team
Send your cat's breed, weight and the space you have, and the PURRZ™ team will tell you which one to order before you spend.
Kitten, adult, senior
Kittens, adults and seniors want different things from the same room.
KittenToys they can carry, a cave they can get into, and a scratching post before the sofa teaches them the alternative. Feathers and string are for play with you, then put away.
Shop kitten-sized play
AdultA proper full-height scratching post, somewhere to be above the room, and a solo-play toy for the hours you are out. Rotate toys weekly; a bored adult cat invents hobbies you will not like.
Shop scratchers
SeniorA bed with a low step-in and a firm base, a scratcher that does not wobble, and shorter, slower play. Stiffness, hiding, or missing the tray are a vet visit first; the right bed comes second.
Shop beds and cavesHealth suitability depends on the diagnosis, symptoms and care plan. Ask a veterinarian before choosing a supportive product.

Four instincts
Four things every cat is built to do. Start with the one your cat is doing to your furniture.

Towers and perches above the room
Wands, feathers, dice and bell balls
Caves, condos, donuts and hammocks
Vet-owned, founder-led. From kittenhood to the senior years, compare scratchers that do not wobble, towers and perches above the room, toys that finish the hunt, and caves and beds with a low step-in for older cats.

A microchip only works once a cat is at a vet or a shelter. A Smart ID Tag works on the street, and a GPS tracker works before anyone finds her at all. Both live in the Ask A Vet app.
Know before you buy: the Smart ID Tag has no live location. The GPS tracker needs charge, mobile coverage and a paid Ask A Vet Tracker Plan; activity and rest data are information, not a diagnosis. Neither replaces a registered microchip.

SCRATCHING
Match the surface and the angle to how your cat already scratches. Rope, felt and cardboard all suit different cats, and placement matters as much as the product.
Before you buy, check
BUSY MINDS
Enrichment can involve stalking, chasing, batting, foraging or problem-solving. Begin with an easy challenge and use part of your cat's normal food allowance.
Before you buy, check
HEIGHT
Cats use height to feel safe as much as to play. Measure the floor space first, then compare perch sizes, stability and how a cat gets from one level to the next.
Before you buy, check
REST & COMFORT
Some cats curl, some sprawl and some only sleep where they cannot be seen. Compare the usable sleeping area, entry height, base stability and cover care.
Before you buy, check
SAFER TRACKING
These tools serve different purposes. A microchip supports permanent identification, a Smart ID tag lets a finder access chosen details, and a powered GPS device can provide live location when coverage and a plan are active.

Meet Dr Duncan Houston
I see cats at their worst hour: the blocked tom at 3 am, the old cat who quietly stopped climbing and nobody noticed, the kitten who ate the string off the wand toy. Most of what comes through the emergency door is normal cat behaviour meeting the wrong environment. PURRZ™ is my attempt to fix the environment: scratching surfaces cats will actually use, caves that give a shy cat a better option than under the bed, toys that finish the hunt, and beds an old cat can get into. Gary tests all of it. He is a Ragdoll, he is leash trained, he comes to the clinic with me, and if he ignores a product it does not go on sale.

Four things we will always tell you before you buy, because a returned scratcher is a cat who went back to the sofa.
A scratcher only works where the cat already scratches. Measure the spot and the footprint before you choose a finish.
Choose the size and material for your cat, supervise vigorous play, and retire anything that splits or sheds pieces small enough to swallow.
A bed can make an old cat's day easier. It does not diagnose or treat anything. New stiffness, hiding or tray changes are a vet visit.
Covers wash, feathers wear out, and a GPS tracker needs a plan. We say so on the product page, not in the fine print.
Short answers from the vet who designs the range. Health questions go to your own vet, or a certified vet in the Ask A Vet app.
Only if it is where the sofa is. Cats scratch to mark and to stretch, in the places they already use, so a post next to the sofa arm works and one across the room does not. Match the direction too: upright rope for cats that stretch up, flat felt or cardboard for cats that scratch sideways. Then make the sofa less appealing for a few weeks.
Measure your cat curled up and stretched out, then check the inner dimensions on the product page; caves should be snug, beds should not. If you are between sizes, email a photo, the breed and the weight to hello@purrz.com and a person will tell you which one to order.
The solo-play toys (Boulder, High Roller Dice, Puzzle Pal) are built to be left out. Wands, feathers and anything on a string are for play with you and then put away: swallowed string is one of the most serious emergencies we see in cats.
First, a vet visit, because a cat that stops jumping usually hurts somewhere and cats hide pain well. Then a bed with a low entry and a firm base, on the floor or a low step, in the spot she already chooses. A bed makes the day more comfortable; it does not treat the reason she stopped.
We ship to most countries, tracked, with the cost and estimate shown at checkout before you pay. The shipping policy has the detail, including what happens if a parcel is late or lost.
Damaged, wrong or faulty is on us: photo, order number, and we replace or refund it under the refund policy. A cat ignoring a new object for a week is normal; put it where she already spends time, rub a little of her own bedding on it, and wait. If it is still wrong after that, write to us and we will do what we can.
No. Location and activity need the Ask A Vet Tracker Plan, sold separately, plus charge and mobile coverage. The Smart ID Tag needs none of those, and has no live location; it opens your cat's profile when someone scans it.
Because they are designed around the cat first and the price second: dense paper rope instead of loose sisal that sheds in a week, felt thick enough to hold its shape, bases heavy enough not to tip, and a vet deciding what goes on sale. Every product page says what it is made of and what it is for, so you can compare.
